英文摘要: Heteroatom-doped carbon materials and 3d transition metals have shown high activity and durability for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER), respectively, but poor bifunctionality. Herein, we use iron and nickel substituted perfluorosulfonic acid/polytetrafluoroethylene copolymer with uniform distribution and conveniently adjustable ratios of metal ions as the pyrolysis precursor to synthesize nitrogen and fluorine co-doped carbon supported FeNi hybrid material. The hybrid material integrates ORR and OER active components together, and exhibits excellent bifunctionality in alkaline medium, demonstrating high performance and cycling durability in rechargeable zinc air battery.
