By using nickel hydroxide-supported gold electrocatalyst (Au/Ni(OH)2), achieve selectivities (77 91%, respectively) densities at moderate potentials (317.7 mA/cm2 0.95 V vs RHE 326.2 1.15 RHE, respectively). We reveal can be enriched Au/Ni(OH)2 interface through their adjacent hydroxyl groups, substantially increasing local concentrations thus densities. As proof concept, employed membrane-free flow electrolyzer triglyceride PET bottles, attaining 11.2 g coupled 9.3 L H2 13.7 9.4 H2, respectively, revealing potential coproduction fuel from in fashion.

Abstract As one of the most promising approaches to producing high‐purity hydrogen (H 2 ), electrochemical water splitting powered by renewable energy sources such as solar, wind, and hydroelectric power has attracted considerable interest over past decade. However, electrolysis process is seriously hampered sluggish electrode reaction kinetics, especially four‐electron oxygen evolution at anode side, which induces a high overpotential. Currently, emerging hybrid strategy proposed integrating thermodynamically favorable electro–oxidation reactions with cathode, providing new opportunity for energy–efficient H2 production. To achieve highly efficient cost–effective toward large–scale practical H production, much work been continuously done exploit alternative anodic oxidation cutting–edge electrocatalysts. This review will focus on recent developments production coupled reactions, including choice substrates, investigation electrocatalytic materials, deep understanding underlying mechanisms. Finally, some insights into scientific challenges now standing in way future advancement technique are shared, hope inspiring further innovative efforts this rapidly growing field.
