Operando Reconstruction toward Dual‐Cation‐Defects Co‐Containing NiFe Oxyhydroxide for Ultralow Energy Consumption Industrial Water Splitting Electrolyzer (Adv. Energy Mater. 10/2023)

Abstract

Water Splitting In article number 2203595, Youwen Liu, Yan Liu, Jiakun Fang, Lin Yu and co-workers fabricate a Co dopant and cation vacancy coexistent NiFe oxyhydroxide by in situ Mo leaching from high-entropy Co, Mo co-doped NiFe hydroxide precursors. Dual-regulated NiFe oxyhydroxide electrodes operate stably at 8 A in practical industrial electrolyzers with ultralow energy consumption of 4.6 kWh m−3 H2, verifying the feasibility of lab-constructed novel catalysts for industrialization.
