Abstract
Abstract Water electrolysis has been expected to assimilate the renewable yet intermediate energy‐derived electricity for green H 2 production. However, current benchmark anodic catalysts of Ir/Ru‐based compounds suffer severely from poor dissolution resistance. Herein, an effective modification strategy is proposed by arming a sub‐nanometer RuO 2 skin with abundant oxygen vacancies to the interconnected Ru clusters/carbon hybrid microsheet (denoted as Ru@V‐RuO 2 /C HMS), which can not only inherit the high hydrogen evolution reaction (HER) activity of the Ru, but more importantly, activate the superior activity toward the oxygen evolution reaction (OER) in both acid and alkaline conditions. Outstandingly, it…
