臭氧是一种清洁的强氧化剂，已被广泛用于有机污染物的降解。但是，单独的臭氧氧化工艺对水中难降解有机污染物的降解效果并不理想。因此，臭氧催化氧化技术应运而生，其中催化剂的选用是影响降解效果的关键因素。从催化剂种类出发，综述了金属氧化物、碳基材料、负载复合型催化剂用于水中污染物臭氧催化氧化处理的作用机理，分析了存在的问题及目前需要解决的主要问题，以期为相关催化剂的研发提供理论依据和参考。

Ozone is a clean and strong oxidant, which has been widely used in the degrading of organic pollutants. However, the ozone oxidation process alone is not ideal for the treatment of difficult?to?degrade organic pollutants in water. Therefore, ozone catalytic oxidation technology came into being, and the selection of catalyst is the key factor to determine its degradation effect. Based on the various types of catalysts, the mechanism of metal oxides, carbon?based materials and supported composite catalysts for the catalytic oxidation treatment of water pollutants by ozone was reviewed. The existing problems and the main problems that need to be solved at present were analyzed to provide theoretical basis and reference for the research and development of suitable catalysts.
