These materials are no dopes : Nitrogen‐doped ordered mesoporous graphitic arrays (NOMGAs) prepared by a metal‐free procedure exhibited higher electrocatalytic activity than the commercially available Pt–C catalyst (see plot), excellent long‐term stability, and resistance to crossover effects in the oxygen‐reduction reaction (ORR). Graphite‐like nitrogen atoms appear to be responsible for the excellent electrochemical performance in the ORR.
