Ruthenium And Silver Synergetic Regulation NiFe LDH Boosting Long‐Duration Industrial Seawater Electrolysis

Abstract The chloride ions in seawater result in corrosion, low catalytic efficiency, and poor stability of the electrocatalysts in direct seawater electrolysis, which limits the use of large‐scale seawater electrolysis technology. Herein, a corrosion‐resistant Ag/NiFeRu layered double hydroxide (LDH) electrocatalyst for seawater electrolysis at industrial current density, in which Ru and Ag species in the catalyst can have a corrosion‐resistance of chloride ions from the anode surface and enhance its robustness in seawater is designed. The catalyst requires the overpotentials of 256 and 287 mV to obtain a current density of 1 A cm −2 in 1 m KOH and 1 m KOH + seawater, respectively. More importantly, it works…
