In this paper,recent progress in the research of Mn-based molecular sieves catalysts for low temperature NH3-SCR is reviewed,and the effects of the main components of MnOx,and additives on the catalyst properties are summarized. The mechanism of H2O and SO2 poisoning of Mn-based molecular sieve catalyst was analyzed. The mechanism of NH3-SCR reaction on Mn-based molecular sieve catalyst was summarized in detail. The application of molecular simulation in molecular sieve catalyst design was introduced. Finally,aiming at the problems existing in the low temperature NH3-SCR for manganese-based molecular sieves,the future development direction and research hotspots of this field are proposed.
