Na3V2(PO4)2F3(NVPF)is regarded as an attractive cathode for sodium ion batteries(NIBs).However,NVPF suffers from low intrinsic electronic conductivity and unsatisfactory diffusion kinetics,which restrict its rate capability and long cycling lifespan.Herein,we propose that a two-dimensional heterostructure consists of uniform NVPF nanoparticles(denoted as n-NVPF)implanted on ultrathin Ti3C2MXene nanosheets(denoted as n-NVPF-TC),featuring enriched V-O-Ti covalent bonds at the heterointerface,where Ti3C2MXene nanosheets not only provide an efficient conductive network for electrons/ions but alleviate stress concentration caused by volume expansion during cycling.Furthermore,the V-O-Ti covalent bonds can stabilize the heterostructure and promote the Na+storage kinetics.Consequently,n-NVPF-TC exhibits remarkable rate capability(64 mAh g-1at 40 C)and ultralong cycling lifespan of 2500 cycles with capacity retention of 80%at 15 C.When coupled with a hard carbon anode,the full cell delivers a high energy density(406 Wh kg-1)and good cyclability.This work provides new insights into understanding the effect of morphology and heterointerface on sodium storage kinetics of cathodes and tremendously promotes the high-rate performance of NIBs. 展开更多

Substituting the sluggish oxygen evolution reaction(OER)with the thermodynamically advantageous hydrazine oxidation reaction(HzOR)represents an effective approach to achieve low-energy hydrogen generation from seawater.However,the advancement of this technology is impeded by the lack of robust bifunctional electrocatalysts capable of driving both the hydrogen evolution reaction(HER)and HzOR at industrially relevant current densities.Herein,a B,P co-doped NiMo-based heterostructure featuring abundant crystalline/amorphous interfaces(Ni3Mo/B,P-NiMoO4)is presented.Under alkaline conditions,the optimized catalyst exhibits exceptional bifunctional electrocatalytic performance,requiring minimal overpotentials of 229 and 124 mV reaching 500 mA cm-2 for HER and HzOR,respectively.Remarkably,the assembled hydrazine-assisted seawater electrolyzer operates at 500 mA cm-2 with an ultralow voltage of 0.372 V for over 380 h.More importantly,experiments and density functional theory(DFT)calculations reveal that the distinct work function difference at the crystalline/amorphous interface induces a strong built-in electric field(BEF).This field,synergistically with B,P co-doping,triggers interfacial charge redistribution and optimizes the d-band center of active sites,thereby significantly accelerating the reaction kinetics.This work provides valuable theoretical insights and a feasible material design strategy for the development of energy-saving seawater electrolysis technologies. 展开更多

Gradient magnetic heterointerfaces have injected infinite vitality in optimizing impedance matching,adjusting dielectric/magnetic resonance and promoting electromagnetic(EM)wave absorption,but still exist a significant challenging in regulating local phase evolution.Herein,accordion-shaped Co/Co3O4@N-doped carbon nanosheets(Co/Co3O4@NC)with gradient magnetic heterointerfaces have been fabricated via the cooperative high-temperature carbonization and lowtemperature oxidation process.The results indicate that the surface epitaxial growth of crystal Co3O4 domains on local Co nanoparticles realizes the adjustment of magnetic-heteroatomic components,which are beneficial for optimizing impedance matching and interfacial polarization.Moreover,gradient magnetic heterointerfaces simultaneously realize magnetic coupling,and long-range magnetic diffraction.Specifically,the synthesized Co/Co3O4@NC absorbents display the strong electromagnetic wave attenuation capability of−53.5 dB at a thickness of 3.0 mm with an effective absorption bandwidth of 5.36 GHz,both are superior to those of single magnetic domains embedded in carbon matrix.This design concept provides us an inspiration in optimizing interfacial polarization,regulating magnetic coupling and promoting electromagnetic wave absorption. 展开更多

The existence of multiple vacancies leads to significant changes in the local atomic structure,which can regulate the electronic structure of the surface and form unsaturated coordination geometries.However,the current methods employed to generate multiple vacancies in two-dimensional(2D)layered double hydroxide(LDH)materials are still difficult to achieve to some extent and are primarily limited to monolayer LDH structures.Here,we present an improved method to synthesize NiMoP/Ni2P catalysts with a sponge-like porous structure.Firstly,NiO with dual defects was constructed by subjecting NiMo-LDH/Ni to air calcination.Subsequently,we performed phosphorization treatment and introduced multiple Ni vacancies and O vacancies as defect sites to tune the edge and substrate surfaces of LDH.At the same time,the electronic structure was tuned by adding P heteroatoms.The synergistic effect of porous structure,heterogeneous interfaces,vacancies,doping defects,and amorphous states can greatly enhance the electron transfer effect inside the catalysts,which significantly improves the catalytic ability of the oxygen evolution reaction(OER).Therefore,the overpotential for the oxygen evolution reaction of NiMoP/Ni2P heterointerfaces reaches 270 mV at a current density of 10 mA·cm-2under alkaline conditions,with the catalysts capable of sustaining high current densities even after the durability testing for 35 h. 展开更多

Solvated zinc ions are prone to undergo desolvation at the electrode/electrolyte interfaces,and unstable H2O molecules within the solvated sheaths tend to trigger hydrogen evolution reaction(HER),further accelerating interfaces decay.Herein,we propose for the first time a novel strategy to enhance the interfacial stabilities by insitu dynamic reconstruction of weakly solvated Zn2þduring the desolvation processes at heterointerfaces.Theoretical calculations indicate that,due to built-in electric field effects(BEFs),the plating/stripping mechanism shifts from[Zn(H2O)6]2þto[Zn(H2O)5(SO4)2-]2þwithout additional electrolyte additives,reducing the solvation ability of H2O,enhancing the competitive coordination of SO42-,essentially eliminating the undesirable side effects of anodes.Hence,symmetric cells can operate stably for 3000 h(51.7-times increase in cycle life),and the full cells can operate stably for 5000 cycles(51.5-times increase in cycle life).This study provides valuable insights into the critical design of weakly solvated Zn2+ þand desolvation processes at heterointerfaces. 展开更多

Interface issues have consistently impeded efforts to balance a trade-off between the conductivity functionality and mechanical properties of Cu-matrix composites.Combining first-principles simulations,this study addresses this challenge by preparing a new Cumatrix composite reinforced with MXene,Cu/Ag@MXene composite block(CuAM-CB),which improves the compatibility between metallic Cu and nonmetallic MXene facilitated by Ag modification anchored in situ onto MXene nanosheets,thus realizing element-coupled reinforcement of Ag at the Cu/MXene heterointerfaces.Benefiting from the strong interaction between Ag and C atoms from in situ self-reduction,as well as the excellent compatibility between Ag and Cu atoms(both IB group metals),Ag atoms act as a mediator for the electron transport and mechanical connection at the Cu/MXene heterointerfaces,enabling CuAM-CB to achieve integrated high conductivity functionality(up to 95%IACS)and strong mechanical properties(with a strength-plasticity product of∼18 GPa%). 展开更多

Heterointerfaces have been pivotal in unveiling extraordinary interfacial properties and enabling multifunctional material platforms.Despite extensive research on all-oxide interfaces,heterointerfaces between different material classes,such as oxides and nitrides,remain underexplored.Here we present the fabrication of atomically sharp heterointerfaces between antiperovskite Ni3InN and perovskite SrVO3.Leveraging layer-resolved scanning transmission electron microscopy and electron energy loss spectroscopy,we identified pronounced charge transfer across the well-ordered interface.First-principles calculations confirmed our experimental observations and further predicted an emergent magnetic moment within the Ni3InN layer due to the charge transfer.These findings pave the way for novel electronic and spintronic applications by enabling tunable interfacial properties in nitride/oxide systems. 展开更多

The development of wearable multifunctional electromagnetic protective fabrics with multifunctional,low cost,and high efficiency remains a challenge.Here,inspired by the unique flower branch shape of“Thunberg’s meadowsweet”in nature,a nanofibrous composite membrane with hierarchical structure was constructed.Integrating sophisticated 0D@2D@1D hierarchical structures with multiple heterointerfaces can fully unleash the multifunctional application potential of composite membrane.The targeted induction method was used to precisely regulate the formation site and morphology of the metal–organic framework precursor,and intelligently integrate multiple heterostructures to enhance dielectric polarization,which improves the impedance matching and loss mechanisms of the electromagnetic wave absorbing materials.Due to the synergistic enhancement of electrospinning-derived carbon nanofiber“stems”,MOF-derived carbon nanosheet“petals”and transition metal selenide nano-particle“stamens”,the CoxSey/NiSe@CNSs@CNFs(CNCC)composite membrane obtains a minimum reflection loss value(RLmin)of-68.40 dB at 2.6 mm and a maximum effective absorption bandwidth(EAB)of 8.88 GHz at a thin thickness of 2.0 mm with a filling amount of only 5 wt%.In addition,the multi-component and hierarchical heterostructure endow the fibrous membrane with excellent flexibility,water resistance,thermal management,and other multifunctional properties.This work provides unique perspectives for the precise design and rational application of multifunctional fabrics. 展开更多

The pervasive adoption of 5th generation mobile communication technology propels electromagnetic wave(EW)absorbents to achieve high-level performance.The heterointerface construction is crucial to the improvement of absorption ability.Herein,a series of ultralight composites with rational heterointerfaces(Co/ZnO@N-doped C/layer-stacked C,MSC)is fabricated by calcination with ration-al construction of sugarcane and CoZn-zeolitic imidazolate framework(ZIF).The components and structures of as-prepared composites were investigated,and their electromagnetic parameters could be adjusted by the content of CoZn-ZIFs.All composites possess excellent EW absorption performance,especially MSC-3.The optimal minimum reflection loss and effective absorption band of MSC-3 can reach−42 dB and 7.28 GHz at the thickness of only 1.6 mm with 20wt%filler loading.This excellent performance is attributed to the syner-gistic effect of dielectric loss stemming from the multiple heterointerfaces and magnetic loss induced by magnetic single Co.The sugar-cane-derived layer-stacked carbon has formed consecutive conductive networks and has further dissipated the electromagnetic energy through multiple reflection and conduction losses.Moreover,the simulated radar cross section(RCS)technology manifests that MSC-3 possesses outstanding EW attenuation capacity under realistic far-field conditions.This study provides a strategy for building efficient ab-sorbents based on biomass. 展开更多

Multiphase polymer-derived ceramics have the advantages of thermal stability and adjustable dielectric properties,which exhibit significant potential for use in high-temperature microwave absorbing materials.Herein,Co-containing polymer-derived SiCN(Co-SiCN)ceramics were successfully synthesized by the physical mixing of zeolitic imidazolate framework(ZIF)-67 and polysilazane precursors and subsequent pyrolysis.The phase and chemical compositions,microstructures,dielectric properties,electromagnetic wave absorption(EWA)performance,and mechanism of the ceramics were investigated.The results showed that the introduction of ZIF-67 promoted the in situ formation of dielectric loss phases,including SiC nanocrystals,CoSi nanocrystals,and free carbon.The phase composition can be regulated by controlling the pyrolysis temperature to achieve ideal EWA properties.The Co-SiCN ceramic pyrolyzed at 1500℃demonstrated excellent EWA performance,with a maximum effective absorption band(EABmax)of 3.0 GHz at an ultralow thickness of 1.05 mm and minimum reflection loss(RLmin)of-46.4 dB at a low frequency of 6 GHz.Compared with other reported SiCN-based ceramics containing magnetic metals,the ceramics prepared in this study stand out because of their low RL and high EAB at low thicknesses.The superior microwave absorption performance of the Co-SiCN ceramics is attributed to the heterointerface polarization,and impedance matching induced by the synergistic effects of their co-existing electromagnetic transparent/absorption phases.This study provides new insights into the development of high-performance SiCNbased microwave absorbers. 展开更多

Superlubricity,a novel lubricity mode ascribing to moirésuperlattice(MSL),has attracted attention in ultra-precise manufacture,microelectronic devices,and national defense areas.Based on incommensurate MSL,nearly zero friction can be achieved by eliminating sliding lock-in and offsetting lateral force in principle,and the theoretical foundations are still under extensive investigation.Here,the effects of MSL-induced lattice distortion onπbond and tribological performance in twist MoS2/graphene and MoS2/BN heterointerfaces were studied by first-principles calculations comprehensively.Various contributions of 2pz orbital electron polarization among AA-,AB-,and AC-stacking symmetry areas in different MSL were reflected by band structures to explain the sensitivity ofπbond to MSL.Theπbond perpendicular to the atomic plane depended closely on interfacial distortion,which can not only influence the local distribution of intralayer bond strength but also determine the interlayer charge redistribution.Meanwhile,the interfacial potential energy was changed with the interlayer interaction fluctuation caused by twist angle and atomic stacking modes.Through evaluating the energy barriers and lateral force,MoS2/BN with a twist angle of 20.79°exhibited superlubricity.Moreover,the connection among sliding energy barriers,twist angles,and specific electronic structures has been bridged paving a path to reveal the superlubricity mechanism of two-dimensional materials withπbond. 展开更多

The heterointerface engineering involving different components or phases represents a desirable strategy for enhancing the sluggish kinetics of hydrogen evolution reaction(HER).However,constructing desired heterointerfaces and elucidating the reaction mechanisms on the interface remains a considerable challenge.In this work,we propose a straightforward electrochemical synthesis strategy to prepare the nickel sulfide-based heterointerfaces for HER.The mechanism of electrochemical synthesis is revealed,wherein metal-thiourea species can be formed at the cathode potential and subsequently oxidized to nickel sulfides at the anode potentials.Leveraging this mechanism,a range of nickel sulfides,including NiS,Ni3S2/NiS,Ni/Ni3S2and Ni3S2,have been successfully synthesized by tuning the potential range of cyclic voltammetry.Among these,the obtained Ni3S2/NiS@CC(CC:carbon cloth)exhibits the smallest overpotential of84 mV at 10 mA·cm-2and high stability.Theoretical calculations further reveal that the combination of NiS and Ni3S2induces electron redistribution at the interface,and thus the Volmer process is effectively promoted with faster water dissociation and OH desorption kinetics.Significantly,the simplicity method coupled with a clear synthesis mechanism and outstanding HER performance highlights its promising potential for practical applications. 展开更多

De... Zinc-air batteries(ZABs) with high energy density and safety are promising as next-generation energy storage systems, while their applications are severely hindered by the sluggish reaction kinetic of air cathodes. Developing a bifunctional catalyst with high activity and durability is an effective strategy to address the above challenges. Herein, a Co3O4/Mn3O4 nanohybrid with heterointerfaces is designed as advanced cathode catalyst for ZABs. Density functional theory calculations show the heterogeneous interface between Co3O4/Mn3O4 can improve the dynamics of carrier transport and thus enhancing the catalytic activity and durability. The Co3O4/Mn3O4 catalyst anchored on reduced graphene oxide(rGO)exhibits high oxygen reduction reaction(ORR) activity with a half-wave potential of 0.86 V, and excellent oxygen evolution reaction(OER) activity with the potential of 1.59 V at 10 mA cm-2 , which are comparable to the commercial noble metal catalysts. The improved ORR/OER catalytic activity is ascribed to the synergistic effect of heterointerfaces between Co3O4 and Mn3O4as well as the improved conductivity and contact area of oxygen/catalysts/electrolytes three-phase interface by r GO. Furthermore, a home-made ZAB based on Co3O4/Mn3O4 GO shows a high open circuit voltage of 1.54 V, a large power density of 194.6 mW cm-2 and good long-term cycling stability of nearly 400 h at 5 mA cm-2 , which affords a promising bifunctional oxygen catalyst for rechargeable ZABs. 展开更多

The two-dimensional electron gas at SrTiO3-based heterointerfaces has received a great deal of attention in recent years owing to their potential for the exploration of emergent physics and the next generation of electronics. One of the most fascinating aspects in this system is that the light, as a powerful external perturbation, can modify its transport properties. Recent studies have reported that SrTiO3-based heterointerfaces exhibit the persistent photoconductivity and can be tuned by the surface and interface engineering. These researches not only reveal the intrinsic physical mechanisms in the photoresponsive process, but also highlight the ability to be used as a tool for novel all-oxide optical devices. This review mainly contraposes the studies of photoresponse at SrTiO3-based heterointerfaces. 展开更多

The coupling of photoanode(Pho)and oxygen evolution catalyst(OEC)is an ideal approach to enhance the photoelectrochemical(PEC)activity.Nevertheless,the anticipated photocurrent density has not been reached due to slow charge transfer dynamics and severe charge recombination at the interface.Herein,a novel“killing two birds with one stone”approach was discovered by employing CoPi as an interface mediator,which shifts its charge transfer behavior from conventional hole storage or passivation to hole transporter.The optimized BiVO4/CoPi/FeOOH photoanode achieves a noteworthy photocurrent density of 5.4 mA/cm2 and exhibits long term stability(13 h).The dynamic analysis and electrochemical characterization reveal that CoPi can rapidly and directly transfer more photogenerated holes to the surface of OEC in comparison to traditional slow holes transfer behavior,resulting in highly efficient interface charge separation.Interestingly,the strong interfacial interactions can also be extended to OEC/electrolyte interface,specifically by promoting the surface reaction dynamics.Moreover,this innovative approach of altering behavior of CoPi can also be utilized to design other photoanodes,like BiVO4/CoPi/NiOOH,aimed at efficient PEC water splitting.This finding affords a smart strategy to develop highly efficient and stable photoelectrodes for water splitting. 展开更多

In this study,graphdiyne(GDY)was grown in situ on sulfide surfaces derived from polyoxometalate(POM)to construct sp-C-S-M heterointerfaces between metal sulfides(Fe3S4and MoS2)and GDY,thereby enabling highly efficient bifunctional oxygen evolution reaction(OER)and hydrogen evolution reaction(HER)electrocatalysis.Experimental results reveal that the heterointerface configuration enhances the synergistic interaction between the POM-derived sulfides and GDY,promoting rapid charge transfer and increasing the number of active sites,which collectively boost the intrinsic catalytic activity.At a current density of 10 mA cm-2,the catalyst demonstrates low overpotentials of 132 mV for the HER and 218 mV for the OER and exhibits excellent catalytic activity.This work systematically clarifies the critical roles of electronic interaction and interfacial architecture between POM-derived components and GDY in enhancing HER and OER activities,offering an effective strategy for the design and construction of high-performance electrocatalysts. 展开更多

To enhance the kinetics of the electrochemical hydrogen evolution reaction(HER)in alkaline electrolytes,metallic Ru(Ru0)-RuO2-ZnO heterointerfaces are constructed by pyrolyzing hollow Ru-ZIF-8 nanostructures with varying shapes.Systematic characterizations and theoretical simulations reveal that the exposed facets and oxygen vacancy(Ov)contents of the heterointerfaces depend on the shape and pyrolysis temperature of Ru-ZIF-8.Rhombic dodecahedral Ru-ZIF-8-derived nanocrystals by pyrolyzing at 900℃expose Ru0{120}-RuO2{221}-ZnO{001}heterointerfaces with suitable Ovcontent,resulting in an alleviated work function and a downshifted d-band center(εd).These structural optimizations accelerate H2O adsorption-dissociation on the nanocrystal surface,weaken the excessively strong electronic interaction between the catalytic surface and the H*intermediate,balance the strengths of H*adsorption and H2desorption,facilitate the rate-determining stage(RDS,H2desorption),and ultimately lower the apparent activation energy for HER.As a result,an overpotential of 25.0 mV at 10 mA cm-2and a turnover frequency of H2generation of 0.23 s-1at 100 mV are achieved,surpassing other heterostructure analogues.An excellent linearity between the HER overpotentials and the Gibbs free energy change of H*adsorption is substantiated,highlighting the advantage of d-orbital manipulation in expediting activity. 展开更多

Lattice-level design presents a promising avenue to overcome the bottleneck of achieving a broadband dielectric response in transition metal chalcogenides.However,the selective control of lattice characteristics(expansion or contraction)in multiphase systems remains challenging,and their specific effects on electromagnetic modulation are poorly understood.Herein,we propose an etching-assisted strain engineering strategy to deliberately trigger lattice distortions and regulate lattice expansion and contraction in cobalt sulfide heterostructures.We demonstrate that the sequence of processing steps is critical:an etching-first-sulfurization-later approach(Route 1)preferentially induces tensile strain and lattice expansion,whereas a sulfurization-first-etching-later(Route 2)pathway favors compressive strain and lattice contraction.Compared to the strain-free cobalt sulfide(C-0),the optimal sample(C-24)achieves a comparable coexistence of local lattice expansion and contraction via Route 1.This coexistence expedites localized lattice perturbations,enriches lattice distortion-related sulfur vacancies,and intensifies multiphase heterointerfaces,collectively boosting the dielectric polarization response.Consequently,this elaborate strategy enables an effective absorption bandwidth of 5.45 GHz with excellent polarization behavior,which are 1.83-fold and 1.93-fold improvement over C-0,respectively.This work provides a novel strategy for manipulating polarization response at the lattice level,offering valuable insights for the rational design of advanced heterogeneous absorbents based on lattice strain engineering. 展开更多

Bismuth-based materials are prevalent catalysts for CO2electroreduction to formate,enduring high hydrogen evolution reactions and inadequate activity and stability.Herein,we reveal that in-situ electrochemical transformation of Cu2BiSxsolid solution into Bi/CuxSyheterointerfaces,which can stabilize the intermediates and achieve highly selective and consistent CO2electroreduction.It shows over 85%Faraday efficiency(FE)of formate with a potential window of−0.8 to−1.2 VRHE(RHE:reversible hydrogen electrode)and a stability above 90%over 27 h in H-type cell at−0.9 VRHE.It maintains more than 85%of FEformate at the current density of−25 to−200 mA·cm−2,has stability of about 80%of FEformate at least 10 h at−150 mA·cm−2in flow cell.In-situ Fourier transform infrared(FT-IR)spectroscopy measurement confirms that the preferred route of catalytic reaction is to generate *CO2 and *OCHO intermediates.The density functional theory(DFT)calculations illustrate that heterointerfaces facilitate the prior process of CO2to HCOOH through *OCHO by additional Bi hybrid orbitals.This study is expected to open up a new idea for the design of CO2electroreduction catalyst. 展开更多

The accumulation of refractory organics in Bayer liquor(pH 14.4)critically compromises aluminum production efficiency and product quality,necessitating sustainable remediation strategies.Herein,we develop an ultrasonic-driven catalytic ozonation system with dynamically reconstructed CuO/Cu2O heterointerfaces,achieving unprecedented efficiency in extreme alkaline wastewater treatment.Atomic-scale interface engineering endows the catalyst with hydrophilicity(contact angle:6.1°)and 3.8–4.3 times higher oxygen vacancy density compared to single-phase catalysts.These properties facilitate efficient interfacial interactions with Bayer liquor and enable superior ozone activation through synergistic Cu(I)/Cu(II)redox cycling across the heterointerface.This interfacial synergy reduces ozone adsorption energy from 5.46 eV(Cu2O)to 1.48 eV,driving the generation of reactive oxygen species(ROS)via low-energy pathways.Under optimized conditions,the system achieves 57.82%TOC removal within 1.5 h with 2.3-fold faster kinetics than ozone–alone processes,while improving energy efficiency by 1.82–3.22 times per kWh over conventional thermal oxidation.Remarkable stability is demonstrated through 80.21%activity retention after 6 cycles,attributed to surface energy minimization(0.61 J m−2),alongside 67.91%hydroxyl radical(•OH)-mediated degradation confirmed by quenching tests.In XPS,EEMs analysis,and ECOSAR modeling further elucidate the surface reconstruction mechanism and intermediate toxicity reduction.This work establishes an atomic interface design paradigm that bridges catalytic innovation with green metallurgy applications,offering a sustainable solution for industrial wastewater remediation aligned with circular economy principles. 展开更多
