Abstract

Developing highly active and sustained oxygen evolution reaction (OER) catalysts for energy-saving electrolytic hydrogen generation is highly attractive. In this work, we report the development of a CuMoO nanosheet array on nickel foam (CuMoO/NF) as a highly active OER catalyst. Such CuMoO/NF shows high catalytic activity in 1.0 M KOH, passing 50 mA cm at an overpotential of 325 mV. It also shows superior long-term durability more than 24 h with a turnover frequency (TOF) of 0.09 mol O s at overpotential of 400 mV.

摘要

开发用于节能电解制氢的高活性且可持续的析氧反应（OER）催化剂极具吸引力。在这项工作中，我们报道了在泡沫镍上制备的CuMoO纳米片阵列（CuMoO/NF）作为一种高活性OER催化剂的进展。这种CuMoO/NF在1.0 M KOH中表现出高催化活性，在325 mV的过电位下通过50 mA cm²的电流密度。在400 mV的过电位下，其周转频率（TOF）为0.09 mol O₂ s⁻¹，还表现出超过24小时的优异长期耐久性。
