摘　　要：ZnO因具有良好的光学活性、无毒和化学稳定性而被广泛应用于光催化领域,但单一的ZnO作为光催化剂时还存在一些缺点,如光生电子空穴(e^(-)h^(+))复合快、对可见光利用率低和生成活性氧物种少等.为提高ZnO的光催化性能,研究人员采用多种方法对ZnO进行改性.总结了近几年ZnO光催化剂的改性手段,其中主要包括元素掺杂、形貌修饰和半导体复合,并简要阐述了ZnO复合材料的催化机理,为进一步提升ZnO的光催化性能及应用提供了参考.ZnO has been widely used in the field of photocatalysis because of its good optical activity,non-toxicity and chemical stability,but there are still some shortcomings when single ZnO is used as a photocatalyst,such as fast photoelectron-hole(e^(-)h^(+))recombination,low utilization of visible light and few reactive oxygen species.In order to improve the photocatalytic performance of ZnO,researchers have adopted a variety of methods to modify ZnO.The modification methods of ZnO photocatalysts in recent years,including element doping,morphology modification and semiconductor composite,are summarized,and the catalytic mechanism of ZnO composites is briefly described,which provides a reference for further improving the photocatalytic performance and application of ZnO.
