Overview

This work demonstrates efficient bifunctional catalysis in Zn–air batteries, suggesting enhanced recharge performance.

Key Points

  • The aim is to develop an efficient bifunctional electrocatalyst for both oxygen reduction and evolution reactions in zinc-air batteries.
  • Utilized NH2-MIL-101(Fe) as a precursor for Fe-NC synthesis via pyrolysis.
  • Synthetized NiFe-LDH on the Fe-NC surface through a wet-chemical method.
  • Evaluated the electrocatalytic performance of Fe-NC@NiFe-LDH in alkaline environments.
  • Fe-NC@NiFe-LDH exhibited a half-wave potential of 0.83 V for ORR.
  • The catalyst demonstrated a low potential of 1.68 V for OER at 10 mA cm−2.
  • The Zn-air battery showed exceptional cycling stability, lasting over 600 hours with 3600 cycles.
