Mesoporous carbon material co-doped with nitrogen and iron (Fe–N–C): high-performance cathode catalyst for oxygen reduction reaction in alkaline electrolyte

Abstract

This work reveals an ordered mesoporous carbon material co-doped with nitrogen and iron (Fe–N–C) for ORR catalysis in an alkaline electrolyte, whose ORR performance surpasses most of the previous metal-free heteroatom-containing carbon materials and is comparable to that of conventional Pt/C in terms of half-wave potential, limiting current density and kinetic current density. A procedure for preparing this Fe–N–C catalyst is described.
