In recent years,due to the commonality of bacterial infections and the emergence of antimicrobial resistance,noninvasive photothermal therapy(PTT)has been increasingly recognized as an effective antibacterial strategy with distinct advantages.Hollow-structured photothermal nanoplatforms are capable of not only enhancing photothermal performance but also serving as multifunctional antibacterial systems through cavity-enabled drug loading and diverse functional components,thus integrating multiple therapeutic modalities in a single platform and exhibiting substantial potential in antibacterial applications.In this review,the design and synthesis strategies of hollow-structured antibacterial materials are summarized,with a particular focus on their photothermal enhancement mechanisms and structure-property relationships.Additionally,the latest advances in hollow-structured photothermal therapy are discussed from the perspectives of diverse synergistic strategies and application scenarios.Finally,the current challenges and future perspectives are highlighted,where intelligent design and large-scale fabrication are expected to pave the way for antibacterial synergistic therapy of hollow structures. 展开更多

Aromatization of light alkanes is a value-added process in both petrochemical and coal chemical industries.Here,single[Ga(OH)]2+ion-exchanged mesoporous hollow-structured ZSM-5(Ga-MH-ZSM-5)material was prepared,and it shows unprecedented catalytic performance in light alkane aromatization,considering activity,product selectivity and catalytic stability.The average aromatics yields in ethane aromatization at 600℃and WHSV of 0.8 h-1 within 28 h and in propane aromatization at 580℃and WHSV of 1.1 h-1 within 20 h reach~18.4%and~70.8%with benzene,toluene and xylenes(BTX)accounting for~96%and~88%of aromatics,respectively.Ga-MH-ZSM-5-0.41 gave a TON for formation of aromatics(TONaromatics)from propane as high as 57479,whereas the reported catalysts maximally show a TONaromatics of 5514.This also holds true for ethane aromatization;the TONaromatics obtained on Ga-MH-ZSM-5-0.41 was³3845 in contrast to£392 on reported non-noble metal catalysts.The catalytic activity of Ga-MH-ZSM-5 highly depends on Ga species structures.[Ga(OH)]2+ions are predominant species at Ga loading≤0.3 wt%,while more[Ga(OH)2]+and GaOx oligomers are formed with increasing Ga content.Upon reduction with H2,[Ga(OH)]2+and[Ga(OH)2]+are transformed into[GaH]2+and[GaH2]+species,which show a propane dehydrogenation rate of 300 and 15 times of that of Brønsted acid sites respectively.The light alkanes are mainly dehydrogenated into light olefins on[GaH]2+species,and then,oligomerized and cyclized into(alkyl)cycloalkanes on H+sites,which is followed by possible ring expansion on H+and sequential dehydrogenations into aromatics primarily on[GaH]2+. 展开更多
