开发高活性和持续析氧反应（OER）催化剂用于节能电解制氢非常有吸引力。在这项工作中，我们报告了泡沫镍 (Cu3Mo2O9/NF) 上 Cu3Mo2O9 纳米片阵列作为高活性 OER 催化剂的开发。这种 Cu3Mo2O9/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 cm(2)。它还显示出超过 24 小时的卓越长期耐久性，在 400 mV 的过电势下，转换频率 (TOF) 为 0.09 mol O-2 s(-1)。
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 Cu3Mo2O9 nanosheet array on nickel foam (Cu3Mo2O9/NF) as a highly active OER catalyst. Such Cu3Mo2O9/NF shows high catalytic activity in 1.0 M KOH, passing 50 mA cm(2) 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-2 s(-1) at overpotential of 400 mV.
