The oxygen reduction reaction (ORR) is an important process in the sustainable energy conversion system such as fuel cells and metal-air batteries. At present, Pt-based catalysts are widely used as catalysts for ORR, but the scarcity and the low durability of Pt and the sluggish reaction kinetics of ORR hinder the large-scale popularization of these energy systems. Herein, we synthesized the metal-free carbon-based catalyst doped with N and P. The obtained N, P co-doped carbon exhibited a high catalytic activity for ORR.
