Caption

Carbon-based catalysts as the potential substitutes for noble metal ones in electrocatalytic oxygen reduction reaction (ORR), have received much research attention. This review introduced the ORR mechanism, analyzed the challenges faced, and discussed the strategies for designing and introducing active sites, enhancing catalyst stability, as well as forming porous structures in carbon-based catalysts.
