Catalyst–Support Interaction in Polyaniline‑Supported Ni3Fe Oxide to Boost Oxygen Evolution Activities for Rechargeable Zn‑Air Batteries

Caption

  • Ni3Fe oxide, with an average size of 3.5 ± 1.5 nm, was successfully deposited onto polyaniline (PANI) support through a solvothermal strategy followed by calcination.
  • The catalyst–support interaction between Ni3Fe oxide and PANI can enhance the Ni-O covalency via the interfacial Ni-N bond.
  • Ni3Fe oxide/PANI-assembled Zn-air batteries achieve superior cycling life for over 400 h at 10 mA cm−2 and a low charge potential of around 1.95 V.
