摘要
ZnO的禁带宽度与TiO2相近,光催化降解机理与TiO2相同,所以ZnO本质上也是一种优良的光催化材料.近年来,有关微/纳米ZnO光催化剂的报道不断增多,但其光催化效率和光化学稳定性仍有待进一步提高.半导体复合法是改善半导体光催化剂性能的一种常用方法.本文中,笔者综述了目前ZnO基双组分复合光催化剂的研究进展,总结概括了ZnO基双组分复合物的光催化机理,并展望了ZnO基复合光催化剂的发展趋势.

Abstract:
Because the wide direct band gap and photodegradation mechanism of ZnO are almost the same as that of TiO2,ZnO is also regarded as an important semiconductor photocatalyst.In the recent years,there have been more and more reports about micro-/nano-ZnO photocatalysts.However,it is still necessary to further enhance the photocatalytic efficiency and the photochemical stability of ZnO.Semiconductor compounding is a common way to improve the performance of semiconductor photocatalysts.This paper reviews the research progress of ZnO-based two-component composite photocatalysts,and summarizes the photocatalytic mechanism of them.The future development trends of ZnO-based composite photocatalysts are evaluated at last.
