Fe-based oxyhydroxides are promising catalysts for oxygen evolution reactions. However, the dynamics of Fe sites require further investigation. Here, the authors report Fe oxyhydroxide clusters on nickel or cobalt oxyhydroxides as key active sites for water oxidation and reveal how these clusters are selectively formed under controlled electrochemical conditions.
