By combining the techniques of electrospinning and heat-treatment, N-doped graphene(NG) were in situ grown on cobalt-containing electronspun carbon nanofibers(CNF) to form three-dimensional(3D) interconnected fiber network structure. The effect of cobalt(Co) content on the oxygen reduction reaction(ORR) activity of the as-prepared samples was studied. It is demonstrated that both the formation of NG and introduction of Co significantly increase the electrocatalytic activity. The hybrid shows optimized ORR p...
