| Abstract | Rechargeable zinc-air batteries (ZABs) have stimulated extensive interests, but the slow reaction kinetics of oxygen reactions hinder their further development. Here a bifunctional oxygen electrocatalyst enriched with both single Fe atoms and NiFe2O4 nanoparticles is designed to mitigate this issue. Specifically, iron phthalocy-anine with single-atom Fe-N4 moiety is coupled with graphene by 7C-7C stacking interaction to accelerate the oxygen reduction reaction (ORR) during discharging, while NiFe-based Prussian blue analogue derived NiFe2O4 nanoparticles are anchored on graphene to promote the oxygen evolution reaction (OER) during charging. The catalyst shows a small overpotential difference of 0.72 V between OER potential at 10 mA cm-2 and ORR half-wave potential. When used as an oxygen electrode catalyst, the corresponding ZAB exhibits a large power density of 185 mW cm-2, a small charge-discharge voltage gap of 0.717 V at 5 mA cm-2, and outstanding dis-charge-charge durability without any decay after 1035 cycles. This work offers a new concept to design multifunctional catalysts and stimulates the development of ZABs. |
