    Abstract

    Fe, N doped 2D porous carbon catalyst was synthesized by pyrolysizing the precursor, ZIF-8, on graphene. Meanwhile, Fe-2,2-bipy were coordinated on ZIF-8. The catalyst was analyzed by SEM, XRD, and XPS for morphology, structure and component. The ORR and OER performance of the Fe, N doped 2D porous carbon catalyst were characterized by RDE, CV curves and LSV curves. It was found that the Fe, N doped 2 D porous carbon catalyst shows uniform 2D structure and that the content of Fe element is 1.32%. The catalyst shows 0.83 V half-wave potentials for oxygen reduction reaction (ORR) in 0.1 mol/L KOH solution and 420 mV over-potential for oxygen evolution reaction (OER) at 10 mA/cm2 in 1 mol/L KOH solution. Then, a zinc-air battery was assembled using as-synthesized catalyst. The power density of zinc-air battery is up to 245 mV/cm2. Furthermore, it shows superior cycling stability.
