Fe,N掺杂二维多孔碳双功能催化剂及锌-空气电池中的应用
Fe, N Doped 2D Porous Carbon Bifunctional Catalyst for Zinc-air Battery
摘要
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 m A/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.关键词
