Nitrous oxide (N2O) is a greenhouse gas almost 300 times more potent than CO2 and an ozone-depleting gas. Electrocatalytic N2O reduction reaction(eN2ORR) allows us to convert N2O to N2 under ambient conditions at room temperature and atmospheric pressure, making electrocatalysis a promising approach for the removal of N2O. Mesoporous carbon supports offer significant potential due to mesopores properties. For instance, mesopores provide highly reactive environments due to their high BET specific surface area for the oxygen reduction reaction. In this study, we explored the electrocatalytic activity of mesoporous carbon supported Pt-Pd-Rh-Sn alloy nanoparticle for nitrous oxide reduction reaction by cyclic voltammetry. We found that alloy nanoparticles on mesoporous carbon with specific mesopore size were higher eN2ORR activity than those on vulcan support and mesopore affect the eN2ORR activity.
