Abstract

(Graph Presented) These materials are no dopes: Nitrogendoped ordered mesoporous graphitic arrays (NOMGAs) prepared by a metalfree 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.
