It is highly desired to enhance the catalytic activity of MnO2 for the oxygen evolution reaction (OER) in alkaline media. Herein we report the development of MnO2-CoP3 nanowires array on Ti mesh (MnO2-CoP3/Ti) as an efficient 3D OER electrocatalyst with good stability under basic conditions. In 1.0 M KOH, the MnO2-CoP3/Ti requires a current density of 10 mA cm(-2) at overpotential of only 288 mV, which is 120 mV less than that for MnO2/Ti. In addition, such MnO2-CoP3/Ti also exhibits high long-term electrochemical durability.
