Self-Supported Co-Mn Oxide Porous Nanosheets Electrode for Enhanced Oxygen Evolution and Seawater Zinc-Air Batteries

Abstract

Rechargeable seawater zinc-air batteries are promising for scalable applications, while high-efficiency oxygen electrocatalysts remain scarce. Herein, self-supported Co-Mn oxide porous nanosheets are fabricated via a facile strategy. The catalyst delivers low overpotentials and superior long-term cycling stability, outperforming noble-metal counterparts for practical seawater battery systems.
