Abstract: The reaction mechanism of NH3-SCR is reviewed,and the recently reported catalyst systems are introduced,such as V-,Mn-,Ce-based transition metal oxide or composite oxide catalysts,Fe-zeolite catalysts and Cu-zeolite catalysts.The advantages and drawbacks of various kinds of catalysts are analyzed.Although there are many kinds of catalyst systems developed for NH3-SCR,some performances of the catalysts like wide operating temperature window,great hydrothermal stability and outstanding resistance to poisoning need to be improved.In the future,it is suggested for NH3-SCR to develop new types of catalysts,improve hydrothermal stability of the catalysts at high temperature,enhance catalysts' resistance to poisoning and develop "green" synthesis process.
