摘要
(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. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA.
