Co2N Nanoparticles Anchored on N-Doped Active Carbon as Catalyst for Oxygen Reduction Reaction in Zinc-Air Battery
文献摘要：
The development of efficient catalytic electrode toward oxygen reduction reaction(ORR)is still a great challenge for the wide use of zinc-air batteries.Herein,Co2N nanoparticles(NPs)anchored on N-doped carbon from cattail were verified with excellent catalytic performances for ORR.The onset and half-wave potentials over the optimal catalyst reach to 0.96 V and 0.84 V,respectively.Current retention rates of 96.8％after 22-h test and 98.8％after running 1600 s were obtained in 1 M methanol solution.Density functional theory simulation proposes an apparently increased electronic states of Co2N in N-doped carbon layer close to the Fermi level.Higher charge density,favorable adsorption,and charge transfer of intermediates originate from the coexistence of Co2N NPs and N atoms in carbon skeleton.The superior catalytic activity of composites also was confirmed in zinc-air batteries.This novel catalytic property and controllable preparation approach of Co2N-carbon composites provide a promising avenue to fabricate metal-containing catalytically active carbon from biomass.
