外文摘要：The pursuit of high-performance is worth considerable effort in catalysis for energy efficiency and environmental sustainability.To develop redox catalysts with superior performance for soot combustion,a series of MnxCoy oxides were synthesized using MgO template substitution.This method greatly improves the preparation and catalytic efficiency and is more in line with the current theme of green catalysts and sus-tainable development.The resulting Mn1Co2.3 has a strong activation capability of gaseous oxygen due to a high concentration of Co3+ and Mn3+.The Mn doping enhanced the intrinsic activity by prompting oxygen vacancy formation and gaseous oxygen adsorption.The nanosheet morphology with abundant mesoporous significantly increased the solid-solid contact efficiency and improved the adsorption capability of gaseous reactants.The novel design of Mn1Co2.3 oxide enhanced its catalytic performance through a synergistic effect of Mn doping and the porous nanosheet morphology,showing significant potential for the preparation of high-performance soot combustion catalysts.
