Abstract

Fe-doped Co₃O₄ polycrystalline nanosheets vertically grown on carbon cloth were developed as self-standing efficient bifunctional electrocatalysts for oxygen reduction and evolution, enabling high-performance Zn–air batteries with a power density of 268.6 mW cm⁻² and superior cycling stability.
