Catalytic technologies have been paid increasing attention in refractory pollutants abatement due to its practical and potential values in water purification. As effective and efficient approaches for water purification, Fenton's reagent, ozonation, electrochemical and photocatalytic methods have been widely studied and applied in different aspects and have been reviewed by several articles. In recent years, some novel catalytic processes based on above processes have been developed for enhancing the efficiency of removing the organics from water. This review emphasized on the recent development of heterogeneous catalytic ozonation, electrocatalysis in respect of novel electrodes and electro-Fenton method, photoelectrocatalysis process and photoelectron-Fenton in water purification. It was also an attempt to propose general ideas about mechanism and principle enhancing the catalytic efficiency for the degradation and the mineralization of organics in water.
催化技术因其在水净化中的实际和潜在价值，在难降解污染物治理方面受到越来越多的关注。作为有效且高效的水净化方法，芬顿试剂、臭氧氧化、电化学和光催化方法已得到广泛研究，并在不同方面得到应用，已有多篇文章对其进行了综述。近年来，基于上述方法开发了一些新型催化工艺，以提高从水中去除有机物的效率。本综述重点介绍了非均相催化臭氧化、新型电极的电催化和电芬顿法、光电催化过程以及水净化中的光电子芬顿法的最新进展。同时，还尝试提出关于提高水中有机物降解和矿化催化效率的机理和原理的总体思路。
