摘 要:光电化学(PEC)传感器具有背景信号低、响应快、灵敏度高的优点,在环境保护和公共健康方面发挥着重要作用。氧化锌(ZnO)作为一种载流子浓度高、生物相容性良好,并且结构稳定的光电材料,在PEC传感领域得到了广泛应用。本文综述了ZnO及其纳米复合材料在PEC传感领域的研究进展。首先,从调控形貌、利用压电效应和引入缺陷工程三个方面,介绍了ZnO结构调控的具体措施。其次,从贵金属和类金属角度总结了金属增强ZnO光电传感性能的应用实例,并梳理了半导体偶联ZnO构建异质结的相关策略。在此基础上,介绍了ZnO基三元复合结构的PEC传感的应用进展。最后,结合ZnO在PEC传感领域的发展现状和未来需求分析,对如何实现高性能、多功能的ZnO基PEC传感器件的进一步开发与应用进行了展望。Photoelectrochemical(PEC)sensors have the advantages of low background signal,fast response,and high sensitivity,and play an important role in environmental protection and public health.Zinc oxide(ZnO),as a photoelectric material with high carrier concentration,favorable biocompatibility,and stable structure,has been widely used in the field of PEC sensing in recent years.This paper reviews the research progress of ZnO and its nanocomposites in the field of PEC sensing.First,the steps for controlling the structure of ZnO are introduced from three aspects:morphology regulation,utilization of piezoelectric effect,and introduction of defect engineering.Second,the applications of metal sensitized ZnO for PEC sensing from precious metals and metalloids are summarized,and the strategies for coupling semiconductors with ZnO to construct heterojunctions are sorted out.On this basis,the application progress of ZnO based ternary composites for PEC sensing is introduced.Finally,based on the current status and future requirements of ZnO in the field of PEC sensing,the prospect of realizing high-performance and multifunctional ZnO-based PEC sensors is discussed.
