摘要：

Pyrolyzing Fe- and N-contained precursor together or separately with graphene results in codoped graphene dominated by bonded or separated Fe and N configuration, respectively. While the Fe£N bonded case greatly enhances activity toward oxygen reduction, the separated one does not. This rationally designed Fe and N codoped 3D graphene exhibits superior electrocatalytic activity than the state-of-the-art Pt/C catalyst. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
