Molten-salt-assisted preparation of porous carbon foams for efficient oxygen electrocatalysis in zinc-air batteries

Abstract

To enhance the reversible electrolytic conversion of oxygen in zinc-air battery, a molten-salt-assisted method was demonstrated to synthesize highly porous carbon foams with in-situ anchoring of metal sites. These electrocatalysts improved the electrolysis for oxygen reduction and evolution reactions, thus leading to fabricate advanced zinc-air battery.
