Abstract

This study investigates oxygen electrocatalytic activities of perovskite-related compounds using a rotating disk electrode technique in an aqueous solution containing lithium chloride and lithium hydroxide. A hydrated oxyhydroxide Ruddelesden–Popper phase, Sr₃Co₂O₅(OH)₂·2H₂O, exhibits excellent performance especially in the oxygen evolution reaction.
