Abstract

Iron and nitrogen co-doped porous carbon nanosheets (Fe,N-PCNs) with a small thickness, smooth surface and high specific surface area are fabricated by a facile bottom-up approach as highly efficient noble metal-free catalysts for the oxygen reduction reaction (ORR). The Fe,N-PCN catalyst exhibits a positive half-wave potential (E1/2) (0.87 V vs. RHE), a similar four-electron pathway in 0.1 M KOH medium, and an excellent long-term stability.
