Abstract

Abstract Proton‐exchange‐membrane water electrolysis (PEMWE) requires an efficient and durable bifunctional electrocatalyst for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Herein, Ir‐based electrocatalyst is designed using the high entropy alloy (HEA) platform of ZnNiC...
