Ir–Ni oxide nanoparticles were simply prepared by stirring IrCl3 and NiCl2 precursors in aqueous base under air. The activities of a series of IrNiyOx nanoparticles with different Ir-to-Ni ratios were measured toward water oxidation in 0.1 M H2SO4. The Ir-to-Ni ratio was 1:0.125 in the most active catalyst (mass normalized > 140 A g− 1 Ir, electrochemically active surface area normalized > 203 A mmol− 1Ir). The stabilized potential for the galvanostatic oxidation (1 mA cm− 2geometric) was as low as 1.51 VRHE, corresponding to 0.28 V in overpotential.
