Summary: A solid solution oxide electrocatalyst (Ir0.3Cr0.7O2) constructed by alloying IrO2 and CrO2 exhibits a lower overpotential (255 mV) for oxygen evolution reaction (OER) in 0.5 M H2SO4 solution compared to the state-of-the-art IrO2 (357 mV). The mass activity of Ir0.3Cr0.7O2 at 1.50 V vs. RHE is 47 times higher than that of IrO2, and it shows excellent stability for OER for more than 200 hours. The enhanced OER activity of Ir0.3Cr0.7O2 is attributed to the enlarged surface-active area, increased active sites for water oxidation, and the formation of high chemical state oxides of Ir due to the leaching of Cr and its strong interaction with Ir sites.
