摘　　要：催化臭氧氧化技术在处理难降解有机废水的应用中具有广阔的前景。催化剂的加入可加快臭氧的分解,使反应在常温常压下进行,并提高氧化能力。文章综述了非均相臭氧催化剂常见催化机理,包括自由基理论、表面络合理论、氧空位理论以及表面氧原子理论。并根据催化剂组成的复杂程度将催化剂分为单独型催化剂(金属型催化剂、碳质材料催化剂)和复合型催化剂(负载型催化剂、掺杂型催化剂),分别介绍了各类催化剂特点及催化性能。基于降低成本、提升重复利用率以及避免二次污染,提高催化剂稳定性,并开发优良的可再生催化剂是未来催化臭氧氧化技术研究开发的趋势。Catalytic ozonation technology has broad prospects in the treatment of refractory organic wastewater.The reaction is carried out under normal temperature and pressure,and the oxidation capacity is improved.The common catalytic mechanism of heterogeneous ozone catalysts is introduced,including free radical theory,surface complexation theory,oxygen vacancy theory and surface oxygen atom theory.According to the complexity of catalyst composition,the catalysts are divided into individual catalysts(metal catalysts,carbonaceous material catalysts)and composite catalysts(supported catalysts and doping type catalysts).The characteristics and catalytic properties of various catalysts are introduced respectively.In order to reduce cost,increase reuse rate,avoid secondary pollution and improve catalyst stability,the development of excellent renewable catalysts is the trend of catalytic ozonation technology research and development in the future.
