The fundamental principle of the SCR De-NOx was introduced. Current research and development situation of V2O5/TiO2,V2O5/SiO2,V2O5/activated coke SCR catalyst were elaborated,the reaction mechanism of V2O5 SCR De-NOx was discussed. In the end,the research direction and future development trend of vanadium catalysts for De-NOx were prospected,such as increasing activity and selectivity of low temperature,developing new type V2O5 catalyst with high activity and better anti-poisoning ability ,and so on.
