The progress of catalytic technologies in water purification： A review

Catalytic technologies have been paid increasing attention in refractory pollutants abatement due to its practical and potential values in water purification. As e ective and e cient approaches for water purification, Fenton’s reagent, ozonation, electrochemical and photocatalytic methods have been widely studied and applied in di erent 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 e ciency 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 e ciency for the degradation and the mineralization of organics in water.
