N-doped porous transition metal-based carbon nanosheet networks as multifunctional electrocatalyst for rechargeable zinc-air batteries

Abstract

The development of cost-effective and highly efficient multi-functional oxygen reduction reaction and oxygen evolution reaction catalysts has attracted much research attention due to their great potential applications in many advanced clean energy storage and conversion technologies. Herein, highly efficient N-doped three-dimensional porous Co–Co3O4/C nanosheet network materials have been developed as bifunctional electrocatalysts for rechargeable zinc–air batteries.
