Ni, Ni/Ir and Ni/Ru electrodeposited electrodes on AISI 316 stainless steel gauze have been studied as electrocatalysts for the oxygen evolution reaction in 5M KOH solution at room temperature. Oxygen evolution on the coated electrodes occurs only after the oxidation of the electrode surface. The Ni/Ir electrode offers a large catalytic activity and a better corrosion resistance in alkaline solution. The electrocatalytic performances obtained by using Ru and Ir elements are discussed.
