Abstract

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.
