The development of efficient electrochemical seawater splitting catalysts for large-scale hydrogen production is of great importance. In this work, we report an amorphous Co-Mo-B film on Ni foam (Co-Mo-B/NF) via a facile one-step electrodeposition process. Such amorphous Co-Mo-B/NF possesses superior activity with a small overpotential of 199 mV at 100 mA cm for a hydrogen evolution reaction in alkaline seawater. Notably, Co-Mo-B/NF also maintains excellent stability for at least 24 h under alkaline seawater electrolysis.
开发用于大规模制氢的高效电化学海水分解催化剂具有重要意义。在这项工作中，我们通过简便的一步电沉积工艺在泡沫镍上制备了非晶态Co-Mo-B薄膜（Co-Mo-B/NF）。这种非晶态Co-Mo-B/NF在碱性海水中析氢反应时具有优异的活性，在100 mA cm下过电位仅为199 mV。值得注意的是，在碱性海水电解条件下，Co-Mo-B/NF至少能保持24小时的优异稳定性。
