ZnO/g-C3N4纳米复合材料光催化降解污染物研究进展徐畅，徐晴川，张晓明，王国宏裏(湖北师范大学稀有金屈化学湖北省协同协创新中心，湖北黃石4加2)摘要：ZnO/g-C3N4纳米复合材料可促进电子-空穴的有效分离，有较大的比表面积，有利于污染物和自由基的扩散和传质，电子可从g-C3N4的导带转移到ZnO的导带上，而空穴可从ZnO的价带转移到g-C3N4的价带上，从而提高复合材料在可见光下的光催化性能，因而ZnO/g-C3N4纳米复合材料在光催化领域中被广泛研究。关键词：g-C3N4;ZnO；纳米复合材料；光催化：文献标识码：A：1672-5425(2016)XX-XXXX-XXResearchprogressinZnO/g-CjN4nanocompositesappliedtothephotocatalyticdegradationofpollutantsXuChang,XuQingchuan,ZhangXiaoming,WangGuohong*(HubeiCollaborativeInnovationCenterforRareMetalChemistry,HubeiNormalUniversity,Huangshi435002,China)Abstract:g-C3N4/ZnOnano-compositematerialscaneffectivelypromotetheseparationofelectronsandholes,andpossesseslargespecificsurfacearea.Itisbeneficialtothediffusionandmasstransferofpollutantsandfreeradicals.Electronscandirectlybetransferredfromtheg-C3N4conductionbandtoZnO,holescanbetransferredfromtheZnOvalencebandtog-C3N4,andcanalsoimprovethephoto-catalyticcapacityofcompositematerialsundervisiblelight.Therefore,ZnO/g-CsN4nano-compositematerialshavewidelybeenresearchedinphoto-catalysisfield.Keywords:g-CsNq；ZnO;nano-composites;photocatalysis4结论与展望ZnO/g-C3N4纳米复合材料在光催化降解污染物方血的应用主要集中在光催化降解冇机染料和去除金属离子上，对环境保护前景广阔。ZnO/g-C3N4纳米复合材料作为一种新型材料在光催化应用中表现出显著的优越性，然而研究的污染物大多数是染料，对水中重金属、无机物、有机污染物，特别是新型难降解污染物的去除与机理还需进一步的研究与发展。参考文献：[11WANGXC,MAEDAK,THOMASA,etaLAmetal-freepolymericphotocatalystforhydrogenproductionfromwaterundervisiblelight]J].NatureMaterials,2009,8(1):76-80.[2]GOUVEACAK,WYPYCHEMORAESSGetal.Semiconductor-assistedphotocatalyticdegradationofreactivedyesinaqueoussolution[J].Chemosphere,2000,40(4):433-440・(3JZHANGJY,ZHANG主题,WANGTM.AnewlumincsccntphcnomcnonofZnOduetotheprecipitatetrappingeffectofMgO(J].Cheminform,2004,35(20):768-770.[4JKOUJH,GAOJ、LIZS,etal.Researchonphotocatalyticdegradationpropertiesoforganicswithdifferentnewphotocatalysts[JJ.CurrentOrganicChemistry,2010,14(7):728-744・齐跃红,刘利，梁英华,等.类石墨相C3N4复合光催化剂[J].化学进展,2015,27(1):38-46.GROENEWOLT\1.NanosUukturirtcmaterialicndurchncuctcmplatsysthcmcundnutzungmesoporosersilikatealsnano-reaktoren[D].Germany:UniversityofPosdam,2004・WANGYJ,SHIR,LINJ,etal.EnhancementofphotocurrentandphotocatalyticactivityofZnOhybridizedwithgraphite-likeC3N4[J].EnergyEnvironmentalScience,2011,4(8):2922-2929.SUNJX,YUANYP.QIULGFabricationofcompositephotocatalystg-C3N4-ZnOandenhancementofphotocatalyticactivityundervisiblelight|J|.DaltonTransactions,2012,41(22):6756-6763.⑼CHENDM,WANGKW,RENTZ,etal.SynthesisandcharacterizationoftheZnO/mpgC3N4heterojunctionphotocatalystwithenhancedvisiblelightphotoactivity[J].DaltonTransactions,2014,43,13105-13114.[10]LIUW,WANGML,XUCX,etal.Significantlyenhancedvisible-lightphotocatalyticactivityofg-C3N4viaZnOmodificationandthemechanismstudy[J].JournalofMolecularCatalysisA:Chemical,2013,368-369:9-15.[111LVHL,激GB,YANGZH,etal.Enhancementphotocatalyticactivityofthegraphite-likeC3N4coatedhollowpencil-likeZnO[JJ.JournalofColloidandInterfaceScience,2015,450:381-387.[12]LIXF,LIM,YANGJH,et“1.Synergisticeffectofefficientadsorptiong-...
