Abstract


  • A Fe-N impregnated carbon in a hybrid with

    in-situ

    grown graphene from hierarchical porous carbon has

    been obtained for high-performance oxygen reduction reaction (ORR) catalysis. This hybrid material

    combines the desirable characteristics for the ORR, including Fe-N active sites, high surface area, good

    electron conductivity, and hierarchical channels for mass diffusion. As a result, this catalyst exhibits a

    very positive reaction onset potential (

    0.05 V

    vs.

    Ag/AgCl), a high ORR current density, and a complete

    four-electron ORR pathway, which are even better than a commercial 20% Pt/C catalyst. We further reveal

    the synergistic ORR enhancement from the controlled Fe-N impregnation in the doped carbon-graphene

    hybrid
