Selenium-doped mixed metal oxide nanoparticles decorated on g-C₃N₄ and MXene sheets as promising bifunctional oxygen electrocatalysts for rechargeable Zn–air batteries

Abstract

Designing bifunctional electrocatalyst to conduct appropriate oxygen reduction reaction (ORR) and oxy-gen evolution reaction (OER) for high performance zinc-air battery is one of the most important challeng-es for sustainable energy...
