摘要

•M(Fe, Co, Mn)/Pr co-doped CeO2 supported highly dispersed Pd catalyst was successfully synthesized.•M(Fe, Co, Mn)/Pr co-doping promotes the formation of oxygen vacancy of CeO2.•Fe doping improves the interaction and electron transport ability between Pd and support.•Pd/FePr-CeO2 catalyst exhibits excellent low-temperature CO oxidation and outstanding H2O resistance.
