摘要

•The NH3-SCR reaction mechanism of Fe-doped and Mn-Fe co-doping catalysts were elucidated.•Mn-Fe co-doping can improve the oxidation capacity of NO and promote the rapid response of SCR.•The dehydrogenation process of NH3 can be promoted by Mn-Fe co-doping.•Mn-Fe co-doping reduces the reaction barrier of the SCR reaction.
