Ethanol is an abundant and sustainable fuel that power direct ethanol fuel cells (DEFCs). In a DEFC, the ethanol oxidation reaction (EOR) proceeds at the anode while the oxygen reduction reaction occurs at the cathode. Conventional DEFC electrocataly

A series of Ir1–xCux (x = 0–0.5) hydrous oxide nanoparticles (HO-np) were prepared simply by stirring solutions of IrCl3 hydrate and CuCl2 hydrate in aqueous KOH under air. Their water oxidation activities were measured in 0.1 M HClO4. The Ir0.89
