MnO2-CoP3 nanowires array: An efficient electrocatalyst for alkaline oxygen evolution reaction with enhanced activity

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 1.0M...

Summary: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 1.0M KOH, the MnO2-CoP3/Ti requires a current density of 10mAcm−2 at overpotential of only 288mV, which is 120mV less than that for MnO2/Ti. In addition, such MnO2-CoP3/Ti also exhibits high long-term electrochemical durability. [Display omitted] •MnO2-CoP3 nanoarray was developed for the first time.•MnO2-CoP3 nanoarray shows superior activity for alkaline water oxidation.•MnO2-CoP3 nanoarray shows high long-term electrochemical durability.
