摘　　要：光催化氧化作为高级氧化技术的一种在环境保护领域具有重要的应用前景。就目前而言,量子效率低、反应速度慢等缺点制约了光催化氧化的应用。投加无机氧化剂能够通过抑制空穴电子对的复合及产生其它氧化物种等方式强化光催化、提高光催化效率,推进光催化在实际中应用的进程。本文较详细地阐述了不同无机氧化剂强化光催化的机理、研究进展,并对无机氧化剂在光催化氧化中的应用前景进行展望。Photocatalysis as one of advanced oxidation processes （AOPs） has good prospect on environmental protection. However, it has some disadvantages keeping back its application, such as low quantum efficiency, low reaction rate. However adding inorganic oxidizing species enhances photocatalytic efficiency by inhibiting the recombination of holes and electrons and by generating other oxidizing species, advancing the practical application of photocatalysis. In this paper, the mechanism of inorganic oxidizing species assisted photocatalysis and research progress are reviewed in detail. At last, the application prospect of inorganic oxidizing species in photocatalysis is forecasted.
