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.

MnO 2 -CoP 3纳米线阵列:一种用于增强活性的碱性氧释放反应的有效电催化剂

迫切需要增强MnO 2在碱性介质中对氧释放反应(OER)的催化活性。在本文中,我们报告了在Ti网孔上(MnO 2 -CoP 3 / Ti)上MnO 2 -CoP 3纳米线阵列的发展,它是一种在基本条件下具有良好稳定性的有效3D OER电催化剂。在1.0 M KOH中,MnO 2 -CoP 3 / Ti在仅288 mV的过电势下需要10 mA cm -2的电流密度,这比MnO 2 / Ti低120 mV 。另外,这种MnO 2 -CoP 3 / Ti也表现出高的长期电化学耐久性。
