Abstract:Photoelectrochemical(PEC) sensors have the advantages of low background signal,fast response,and high sensitivity,and playan important role in environmental protection and public health.Zinc oxide(ZnO),as a photoelectric material with high carrierconcentration,favorable biocompatibility,and stable structure,has been widelyused in the fieldofPEC sensing inrecent years.This paperreviews the research progressof ZnOand its nanocomposites in the fieldof PEC sensing.First,the steps forcontrolling thestructureof ZnOare introduced from three aspects:morphology regulation,utilizationof piezoelectriceffect,and introductionof defect enginering.Second, theapplications of metal sensitized ZnO for PEC sensing from precious metals and metallids are summarized,and the strategies forcoupling semiconductors with ZnO to construct heterojunctionsaresortedout.Onthis basis,the applicationprogress of ZnO based ternary composites forPECsensing is introduced.Finally,based on thecurrent statusand futurerequirementsof ZnOinthefieldofPECsensing,theprospectofrealizing high-performanceand multifunctional ZnO-based PEC sensors is discussed.
