A stable N-doped NiMoO4/NiO2 electrocatalyst for efficient oxygen evolution reaction

N-doped NiMoO 4 /NiO 2 nanorods were fabricated via hydrothermal method and chemical vapor deposition. It exhibited outstanding OER performance with a low overpotential of 185.6 mV to achieve 10 mA cm −2 and was stable at 10 mA cm −2 for 90 h.
