In this study, N,P co‐doped graphene (NPG) was prepared by a one‐step pyrolysis using a mixture of graphene oxide and hexachlorocyclotriphosphazene (HCCP), in which HCCP was used as both the N and P source. Furthermore, it is shown that NPG electrodes, as efficient metal‐free electrocatalysts, have a high onset potential, high current density, and long‐term stability for the oxygen reduction reaction.
