A vertically oriented ternary metal (oxy)hydroxide nanostructure is a sacrificial template of an interconnected metal-organic network on the surface of the carbon cloth (Fe doped MOF ZnNiCoSe@CC nanosheet). The Fe doped MOF ZnNiCoSe@CC nanosheet demonstrates strong and effective multi-functional electrocatalysts, including oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER) in alkaline media together with favorable electrode kinetics. As a solid evidence observational study, the nanostructured Fe doped MOF ZnNiCoSe@CC is often used as air-cathode materials in the rechargeable metal-air battery. The developed zinc-air battery device showed higher open-circuit voltage, higher capacity, and peak power density, excellent discharge–charge performance, and long cycle life. |
