Catalytic oxidation represents a pivotal technology for the valorization of light hydrocarbons,where oxidative dehydrogenation(ODH)and epoxidation reactions using molecular oxygen have garnered substantial interest owing to their high atom economy and environmental friendliness.This review systematically summarizes recent advances in the oxidative dehydrogenation of light alkanes(ethane,propane)and the aerobic epoxidation of light olefins(ethylene,propylene).In terms of rational catalyst design,this review elaborates on performance regulation strategies for metal oxide catalysts such as MoVNbTeOxmixed oxides,NiO-based,and V-based systems,as well as carbon/boron-based non-metal catalysts in alkane oxidative dehydrogenation,along with silver-based and copper-based catalysts in alkene epoxidation.These strategies include regulating the oxidation state of active sites,strong metal-support interactions,particle size and crystal facet engineering,and promoter modification.At the mechanistic level,combining density functional theory calculations with in situ characterization techniques,this review delves into the C-H bond activation and alkene desorption pathways in oxidative dehydrogenation,along with the oxygen insertion routes and competing side reactions in epoxidation.Special attention is given to the dynamic evolution of electrophilic and nucleophilic oxygen species and their decisive role in reaction selectivity.Finally,the review outlines persistent challenges in the field,including suppressing over-oxidation and overcoming the trade-off between conversion and selectivity and proposes future research directions such as the precise design of active centers,development of inherently safer processes,and in-depth analysis of complex reaction networks,aiming to support the green transition of the chemical industry. 展开更多

The electrochemical oxidation of biomass-derived platform molecule 5-hydroxymethylfurfural(HMF)represents a crucial pathway for green transformation into high-value chemicals,yet its reaction pathway selectivity,efficiency,and catalyst stability are strongly dependent on the electrolyte pH environment.Under alkaline conditions,high OH−concentration facilitates preferential aldehyde group oxidation and efficient deprotonation,enabling highly efficient synthesis of 2,5-furandicarboxylic acid,but simultaneously induces HMF self-degradation and complicates product separation.As pH decreases,the reaction mechanism shifts toward enhanced hydroxymethyl oxidation,leading to intermediate accumulation(such as 5-hydroxymethyl-2-furancarboxylic acid,2,5-diformylfuran,and 5-formyl-2-furancarboxylic acid)with challenging selectivity control and significantly slowed reaction kinetics.This review comprehensively examines the systematic differences in HMF oxidation pathways and surface catalytic mechanisms across the full pH range from alkaline to acidic conditions.Addressing the distinct reaction characteristics and core challenges in alkaline,near-neutral,and acidic media,we systematically evaluate design strategies for high-efficiency electrocatalysts and explore reactor design aspects.Future research should focus on process integration(with tailored reactor design)for energy consumption reduction in alkaline systems,targeted synthesis of diverse oxidation products in near-neutral systems,and innovative catalyst development for acidic systems,thereby advancing the efficiency,selectivity,and practical application of HMF electrooxidation technologies across the entire pH spectrum through synergistic optimization of catalyst,reactor,and process. 展开更多

In response to the critical national demand for upgrading automotive gasoline quality,the concept of dual reaction zones was developed to intensify both olefin generation and conversion.The successful largescale implementation of this process has yielded substantial economic benefits and spurred the invention and systematic study of the diameter-transformed fluidized bed(DTFB)reactor,leading to a suite of new catalytic processes.This study begins with the conceptual origins of the DTFB reactor.By analyzing unimolecular and bimolecular mechanisms in hydrocarbon catalysis,the key conditions necessary for maximizing target products are identified.Furthermore,it elucidates the scientific and technological challenges in applying diameter variation to partition the reaction section,highlighting that the primary challenge lies in achieving precise coupling between flow and reaction multimodalities,which necessitates a generalized drag model for accurate prediction of flow regime transitions.Since flow structure is influenced by both macroscopic parameters and local dynamics,a two-way coupled energy minimization multi-scale(EMMS)drag model and a corresponding multi-scale computational fluid dynamics(CFD)approach have been proposed,laying a theoretical foundation for quantitative design of diameter-transformed sections.The subsequent development of ancillary technologies has provided the necessary engineering safeguards for flexible control of temperature,density,and gas-solid contact time in each zone,ultimately enabling the industrialization,large-scale operation,and long-term stability of DTFB-based catalytic technology.Finally,the study outlines several typical processes and their application performance,and prospects future work. 展开更多

The key challenge of water electrolysis is the high energy barrier of the oxygen intermediate of the oxygen evolution reaction(OER)and the unclear catalytic active sites.The recycling of valuable metals from spent batteries and their reconstruction into high-performance electrolytic water catalysts offers significant economic and environmental benefits.In this work,we report a Co3O4/NiFe-layered double hydroxide heterostructure electrocatalyst by reconstruction of spent LiCoO2cathode material through microwave plasma treatment and then compositing with NiFe-layered double hydroxides through a simple hydrothermal method.This catalyst achieves a low overpotential of 235 mV at 10 mA cm-2for OER and exhibits prolonged stability at high current densities when integrated into an alkaline electrolyzer,which surpasses commercial IrO2.In situ spectral analysis and density functional theory demonstrate that the presence of heterostructures between Co3O4 and NiFe-LDH optimizes the charge transport path and reduces the interface resistance.Specifically,the charge redistribution optimizes the adsorption energy of oxygenated intermediates on the Ni and Fe sites,thereby optimizing the reaction pathway and significantly improving the overall OER catalytic efficiency.This work provides a green and scalable way to convert spent metal sources into high-value electrocatalysts,while addressing critical challenges in energy storage and sustainable hydrogen production. 展开更多

The facet effect of metal-organic frameworks(MOF)on regulating the property of loaded co-catalysts is an important but unexplored issue in the field of photocatalysis.In this work,a series of MIL-125-NH2polyhedrons(MIL=Materials Institute Lavoisier)with facet exposure of{001},{001}/{111}and{111}are synthesized and used to load Pd-based co-catalysts for photocatalytic oxygen reduction reaction(ORR)toward H2O2production.The different facets with distinct chemical environments(Ti-O clusters on{111}facets and carboxyl ligands on{001}facets)result in the selective loading of Pd0and PdO dominated cocatalysts on{001}and{111}facets,respectively.The{001}/{111}co-exposed MIL-125-NH2thus enables the spatially separated loading of Pd0and Pd O dual cocatalysts respectively.Pd0efficiently traps the photoexcited electrons and PdO trends to capture the holes,collaboratively promoting the directional separation of photogenerated electron-hole pairs.As a result,the photocatalytic ORR activity is significantly enhanced with a H2O2production rate of 128.6 mmol L-1g-1h-1,superior than pristine and single cocatalyst modified MIL-125-NH2samples.Our findings provide new insight into the design of high-performance photocatalysts. 展开更多

Artificial photosynthesis of hydrogen peroxide(H2O2)from earth-abundant water and oxygen is a sustainable approach,however current photocatalysts suffer from low production rate and solar-to-chemical conversion efficiency(<1.5%).Herein,we report that nickelchromium layered double hydroxide with intercalated nitrate(NiCrOOH-NO3)and a thickness of~4.4 nm is an efficient photocatalyst,enabling a H2O2production yield of 28.7 mmol g-1h-1under visible light irradiation with3.92%solar-to-chemical conversion efficiency.Experimental and computational studies have revealed an inherent facet-dependent reduction-oxidation reaction behavior and spatial separation of photogenerated electrons and holes.An unexpected role of intercalated nitrate is demonstrated,which promotes excited electron—hole spatial separation and facilitates the electron transfer to oxygen intermediate via delocalization.This work provides understandings in the impact of nanostructure and anion in the design of advanced photocatalysts,paving the way toward practical synthesis of H2O2using fully solar-driven renewable energy. 展开更多

MXenes are a family of two-dimensional(2D)layered transition metal carbidesitrides that show promising potential for energy storage applications due to their high-specific surface areas,excellent electron conductivity,good hydrophilicity,and tunable terminations.Among various types of MXenes,Ti3C2Tx is the most widely studied for use in capacitive energy storage applications,especially in supercapacitors(SCs).However,the stacking and oxidation of MXene sheets inevitably lead to a significant loss of electrochemically active sites.To overcome such challenges,carbon materials are frequently incorporated into MXenes to enhance their electrochemical properties.This review introduces the common strategies used for synthesizing Ti3C2Tx,followed by a comprehensive overview of recent developments in Ti3C2Tx/carbon composites as electrode materials for SCs.Ti3C2Tx/carbon composites are categorized based on the dimensions of carbons,including 0D carbon dots,1D carbon nanotubes and fibers,2D graphene,and 3D carbon materials(activated carbon,polymer-derived carbon,etc.).Finally,this review also provides a perspective on developing novel MXenes/carbon composites as electrodes for application in SCs. 展开更多

The development of efficient Cu-based heterogeneous catalysts for CO2 hydrogenation to methanol has been an appealing subject.Inspired by the concept of inverse catalysts,a series of La2O2CO3/Cu nanorod composites with varying Cu contents(denoted as LOC/Cu-x,where x stands for the mass ratio of La and Cu in the catalysts)were prepared by combining coprecipitation and calcination processes.Remarkable composition-dependence of catalytic activity and selectivity were observed when different LOC/Cu-x(x=0.1,0.2,0.5,1,3 and 5)were used to catalyze the CO2 hydrogenation.The predominant product shifted from methane to methanol with the increasing Cu content.The highest reaction rate(13.3 mmol·gCu-1·h-1)and methanol selectivity(85.5%)were achieved when LOC/Cu-1 was tested at 200℃.The LOC was not active for the reaction,while the Cu itself displayed poor catalytic performance.The Cu–LOC interactions significantly affected the nature of the catalysts,including mutual electron transfer,crystal structure,morphology,porosity,surface Cu valence and capability of adsorbing the reactant gases,etc.,which account for the outstanding behavior of the LOC/Cu-1 catalyst.This work provides a new strategy for the design and optimization of Cu-based catalysts. 展开更多

Electrocatalytic water splitting is a highly promising method for green hydrogen production,which is highly important for sustainable and low-carbon societal development.Despite tremendous scientific and technological efforts dedicated to thisfield,its practical application faces challenges owing to heavy energy consumption,mostly from the elevated potentials needed for the oxygen evolution reaction(OER)at the anode[1].Strategies such as developing efficient OER electrocatalysts and using sacrificial agents or electrosynthesis-assisted water splitting have emerged,collectively known as‘‘electrocatalytic hydrogen production trilogy”[2,3].While the latter two strategies show potential,especially the last one,they are still in the early development stages.Currently,there is a pressing need for efficient OER electrocatalysts to promote the commercialization of electrocatalytic water splitting. 展开更多

Increasing the utilization efficiency of platinum is critical for advancing proton exchange-membrane fuel cells(PEMFCs).Despite extensive research on catalysts for the cathodic oxygen reduction reaction(ORR),developing highly active and durable Pt-based catalysts that can suppress surface dealloying in corrosive acid conditions remains challenging.Herein,we report a facile synthesis of bimetallic ultrathin PtM(M=Mo,W,and Cr)nanowires(NWs)composed of group VI B transition metal atomic sites anchored on the surface.These NWs possess uniform sizes and well-controlled atomic arrangements.Compared to PtW and PtCr catalysts,the PtMo0.05 NWs exhibit the highest half-wave potential of 0.935 V and a mass activity of 1.43 A·mgPt−1.Remarkably,they demonstrate a remarkable 23.8-fold enhancement in mass activity compared to commercial Pt/C for ORR,surpassing previously reported Pt-based catalysts.Additionally,the PtMo NWs cathode in membrane electrode assembly tests achieves a remarkable peak power density of 1.443 W·cm−2(H2-O2conditions at 80℃),which is 1.09 times that of commercial Pt/C.The ligand effect in the bimetallic surface not only facilitates strong coupling between Mo(4d)and Pt(5d)atomic orbitals to hinder atom leaching but also modulates the d-states of active site,significantly optimizing the adsorption of key oxygen(*O and*OH)species and accelerating the rate-determining step in ORR pathways. 展开更多

Asymmetric Suzuki-Miyaura couplings have proven to be a powerful method towards the efficient and stereoselective construction of diverse stereogenic elements.However,the construction of planar chirality with such methodology has been rarely explored.Here we demonstrate the enantioselective synthesis of planar chiral pillar[5]arenes via asymmetric Suzuki-Miyaura coupling,leading to the successful synthesis of a wide range of planar chiral pillar[5]arenes with wide diversity in both structure and functionality.In addition,facile derivatizations of the resultant planar chiral pillar[5]arenes further enable the synthesis of a giant“ring on ring”macrocycle as an excellent circularly polarized luminescence(CPL)emitter with a dissymmetry factor(glum)of-0.021,highlighting the great potential of such synthetic methodology for the creation of novel chiral luminescent materials.This work not only extends the asymmetric cross-coupling methodologies for chiral synthesis but also contributes promising chiral building blocks for widespread applications. 展开更多

Although rotaxane dendrimers have shown extensive applications in stimuli-responsive materials,photocatalysis,and chiral luminescent materials,the detailed elucidation of their stimuli-induced motion behaviors remains a major challenge primarily attributed to the dynamic and complicated three-dimensional architectures.Herein,we present the first successful preparation of a new family of selectively-deuterated rotaxane dendrimers,in which deuterated pillar[5]arene wheels were precisely distributed on different generations of the dendrimer skeleton.In particular,the third-generation fully-deuterated rotaxane dendrimer with 28 deuterated[2]rotaxane units was successfully synthesized,enabling the deuteration of 1,400 hydrogen atoms.More importantly,the introduction of acetate anions at varying ratios induced differential contraction motions across different generations of the rotaxane dendrimer,as systematically investigated using a combination of 1H NMR and small-angle neutron scattering(SANS)techniques,providing fundamental insights into the operational mechanism of molecular machines and the cooperative behavior of dynamic systems for further development of novel smart nanodevices and materials. 展开更多

Aiming at the construction of novel multistate circularly polarized luminescence(CPL)switches,dual stimuli-responsive chiral[2]rotaxanes towards anions and light have been designed and constructed.Through the light-controlled on/off F?rster resonance energy transfer(FRET)switching between the emissive stoppers and anion-induced controllable motions of the chiral wheel for the precise regulations of chirality information transfer from the chiral wheel to the emissive stoppers,precisely switching between four CPL emission states with varied emission wavelengths and dissymmetry factors has been successfully realized,making them a promising platform for practical uses such as information storage and encryption.This proof-of-concept study not only provides a novel design strategy for multistate CPL switching but also contributes excellent candidates for the construction of novel smart chiral luminescent materials. 展开更多
