NixWO2.72 nanorods as an efficient electrocatalyst for oxygen evolution reaction

Ni(II) is inserted into the defective perovskite-type WO2.72 nanorods and is stabilized to show Ni(II) composition dependent electrocatalysis with Ni0.78WO2.72 2being the most efficient catalyst, even outperforming the commercial Ir-catalyst, for the oxygen evolution reaction in 0.1 M KOH.540
