The pursuit of high-performance is worth considerable effort in cataly.is for energy.efficiency.and environmental sustainability. To develop redox cataly.ts with superior performance for soot combustion, a series of Mn_(x)Co_(y. oxides were sy.thesized using MgO template *** method greatly.improves the preparation and cataly.ic efficiency.and is more in line with the current theme of green cataly.ts and sustainable development. The resulting Mn_(1)Co_(2.3) has a strong activation capability.of gaseous oxy.en due to a high concentration of Co^(3+) and Mn^(3+). The Mn doping enhanced the intrinsic activity.by.prompting oxy.en vacancy.formation and gaseous oxy.en 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 Mn_(1)Co_(2.3)oxide enhanced its cataly.ic performance through a sy.ergistic effect of Mn doping and the porous nanosheet morphology. showing significant potential for the preparation of high-performance soot combustion cataly.ts.
