Abstract

Sluggish oxygen electrochemistry including both oxygen evolution reactions (OER) and oxygen reduction reactions (ORR) greatly restricts the performance of rechargeable metal-air battery. Herein, we couple NiFe sulfide (NiFeS₂) with S-doped graphene oxide (S-GO) via a simultaneous sulfurization strategy to significantly improve the OER and ORR activities. The NiFeS₂/S-GO on glassy carbon yields an OER current density of 10 mA cm⁻² at 1.47 V and an ORR half-wave potential at 0.74 V (vs. RHE), giving an overvoltage difference as low as 0.73 V. When assembled in a rechargeable Zn-air battery, the battery with NiFeS₂/S-GO air electrode exhibits a steady charging potential (1.98 V) with very little decay in discharging potential (from 1.20 to 1.17 V) for 180 charging-discharging cycles at 10 mA cm⁻². Our study provides new insights for the design of efficient bifunctional oxygen electrocatalysts for high-performance energy conversion and storage devices. © The Royal Society of Chemistry.
