A three-dimensionally structured electrocatalyst: Cobalt-embedded nitrogen-doped carbon nanotubes/nitrogen-doped reduced graphene oxide hybrid for efficient oxygen reduction

Journal Article


Abstract


  • To develop low-cost and efficient oxygen reduction

    reaction (ORR) catalysts, a novel hybrid comprising

    cobalt-embedded nitrogen-doped carbon nanotubes and nitrogen-

    doped reduced graphene oxide (Co-NCNT/NrGO-800)

    was simply prepared by pyrolysis. The combination of nanotubes

    and graphene, and the efficient doping with cobalt

    and nitrogen, greatly contribute to the excellent ORR performance.

    This optimized Co-NCNT/NrGO catalyst exhibits

    a positive onset potential of 0.91 V and a half-wave potential

    of 0.82 V, combined with a relatively low peroxide yield,

    better durability, and better methanol tolerance than commercially

    available Pt/C, which makes it a promising candidate

    as a low-cost and effective non-precious-metal ORR catalyst.
