Uniform nickel–cobalt nanoparticles embedded in nitrogen-doped carbon nanofibers for highly active and durable oxygen reduction electrocatalysts

Abstract

Novel nickel–cobalt bimetallic nanoparticles uniformly embedded in nitrogen-doped carbon nanofibers (NiCo@NCNFs) have been fabricated via a facile electrospinning and subsequent carbonization process, which exhibits a high half-wave potential and excellent long-term stability.
