S-Vacancy Rich Ni-Doped CoS Embedded in S,N Co-doped Carbon as a Bifunctional Catalyst for Zinc–Air Battery

Abstract Simultaneously optimizing activities of oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) remains challenging in the design of bifunctional electrocatalysts due to their distinct reaction pathways. Herein, a simultaneous sulfidation-carbonization strate...
