Abstract
Abstract Alkaline water electrolysis (AWE), as a premier technology to massively produce green hydrogen, hinges on outstanding oxygen evolution reaction (OER) electrodes with high activity and robust stability under high current densities. However, it is often challenged by issues such as catalytic layer shedding, ion dissolution, and inefficient bubble desorption. Herein, a scalable corrosion‐electrodeposition method is presented to synthesize nickel–iron layered double hydroxide (NiFe‐LDH)/Ni 3 S 2 heterostructures on nickel mesh, tailored to meet the stringent requirements of industrial AWE. The study underscores the critical role of the built‐in electric field (BEF) in optimizing electronic properties,…
