Abstract:

In recent years,the advanced oxidation processes(AOPs) in which the free radicals(·OH) is generated has been paid more and more attentions for its advantage on the degradation of refractory organic pollutants.As a new form of AOPs,heterogeneous catalytic ozonation could combine the oxidizing capacity of ozone with the adsorption and catalysis of adsorbent quite well,which obtains higher mineralization of organisms.Most of researches show that the catalysts play an important role in the purifying process of different organisms.The mechanisms of catalytic ozonation are introduced briefly first,and then the catalysts recently used in this process are summarized in detail.

Key words: heterogeneous catalysis, ozonation, catalyst
