开发高性能的酸性介质中水裂解制氢非贵金属电催化剂正受到越来越多的关注。本文介绍了一种制备Ni-Mo涂层珊瑚状铜微阵列的两步电化学法：(I)方波脉冲处理光滑的铜衬底；(Ii)诱导共沉积Ni-Mo涂层。所制备的电极在酸性介质中对析氢反应(HERS)表现出接近铂电极的高电催化活性。用连续循环伏安法(CV)和计时电流法评价了所制备电极在酸性介质中的稳定性。该电极电催化活性的提高归因于其较高的比表面积以及镍和钼之间的协同作用。在酸性介质中，Ni-Mo涂层珊瑚状铜微阵列电极是一种很有前途的HER电催化剂候选电极。
Development of high-performance non-precious metal electrocatalysts for hydrogen production from water splitting in acidic media is attracting more and more interests. We describe here a two-step electrochemical method to prepare Ni-Mo coated coral-like Cu micro-arrays:(i) treatment of a smooth Cu substrate with square wave potential pulses and (ii) induced co-deposition of Ni-Mo coatings. The prepared electrode demonstrates high electrocatalytic activity close to a Pt electrode for hydrogen evolution reactions (HERs) in an acidic medium. The stability of the prepared electrode in the acidic medium is assessed by continuous cyclic voltammetry (CV) and by chronoamperometry. The enhanced electrocatalytic activity of this electrode is attributed to the high surface area and the synergistic interaction between Ni and Mo. The electrode of Ni-Mo coated coral-like Cu micro-arrays is a promising candidate of electrocatalysts for HERs in acidic media.
