Development of synthesis procedures of efficient amorphous heteroatom coupling interfaces is important for the improvement of electrocatalyst performance. Herein, the Co/Ni NWs/NF composite electrode was prepared using magnetic effect, where Ni nanowires were initially grown on Ni foam to increase its specific surface area, followed by the electrodeposition of amorphous cobalt nanosheets to form multiple active sites for the hydrogen evolution reaction (HER).The electrochemical results show that the prepared Co/Ni NWs/NF can deliver a current density of 10 mA cm^-2 at an overpotential of 49 mV in 1 M KOH electrolyte. The physical test results demonstrate that the introduction of cobalt species onto Ni nanowire result in the interface coupling effect, which can efficiently increase the HER active surface sites and modify the interface charge distribution. The study provides new approach for design and preparation of highly active hydrogen evolution catalysts for water electrolysis.

开发高效无定形杂原子偶联界面的合成程序对于提高电催化剂性能具有重要意义。在此，Co/Ni NWs/NF 复合电极是利用磁效应制备的，其中 Ni 纳米线最初生长在 Ni 泡沫上以增加其比表面积，然后电沉积非晶钴纳米片以形成多个析氢活性位点反应 (HER)。电化学结果表明，所制备的 Co/Ni NWs/NF在 1 中可在 49 mV 的过电势下提供 10  mA  cm ^{-2的电流密度}  M KOH 电解质。物理测试结果表明，将钴物种引入Ni纳米线会产生界面耦合效应，可以有效增加HER活性表面位点并改变界面电荷分布。该研究为设计和制备用于水电解的高活性析氢催化剂提供了新的途径。
