摘要

Rechargeable Zn-air batteries gained significant attention in the past few years, due to their low cost, environmentally friendliness,and high theoretical specific energy density [1].However, with slowness and complexity of reactions in the air electrode during working condition, rechargeable Zn-air batteries cannot be good at engineering practice.Surface defects of catalyst can serve as active sites for adsorption and chemical transformations in oxygen reduction reaction (ORR)/oxygen evolution reaction (OER) [2].
