Regulating the selective adsorption of OH* over the equatorial position of Co3O4via doping of Ru ions for efficient water oxidation reaction

The synthesized Ru-Co 3 O 4 delivers a high performance towards the OER in alkaline (292 mV) and acidic (365 mV) media. Structural optimization demonstrates the distortion of bond length favours the selective adsorption of OH − which facilitates the OER.
