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.
