Nowadays,NOx pollution becomes more and more serious ,low temperature SCR denitra-tion technology,as a kind of new and potential denitration technology,has attract people′s attention. Gives a summary and commentary on the research status of low temperature SCR denitration catalysts and mainly introduces the scientific research status of manganese catalysts,vanadium cata-lysts and other metal oxide catalysts. Indicates the different types of catalyst preparation methods, carriers,and the use of different kinds of metal oxides may all have influence on the catalyst activity and the efficiency of denitrification. Meanwhile,the denitration mechanism of low-temperature SCR catalysts is introduced. At last ,elaborates the effects of water vapor and SO2 in fuel gas on catalytic process.
