摘要：

为满足大规模电解水制氢对低成本、高效能非贵金属催化剂的需求，开发了一种可规模化制备的高活性非贵金属析氢反应（HER）钒镍（VNi）薄膜电催化剂。采用磁控共溅射技术，在自支撑碳纸电极上调整适当的掺杂程度，Ni靶直流功率设定为120 W， 制备了不同原子比的NiV薄膜催化剂。结果表明：NiV25样品催化剂（V靶射频电源25 W），在碱性介质析氢反应中，过电位低至42.3 mV（对应10 mA/cm2电流密度），Tafel斜率为125.17 mV，具突出的稳定性；可对NiV50样品催化剂（V靶射频电源50 W），在10 mA/cm2电流密度下持续运行100 h。

Abstract:

A highly active non-precious metal vanadium-nickel (VNi) thin-film electrocatalyst was developed for the hydrogen evolution reaction (HER) with scalable preparation to meet the demand for the low-cost, high-performance non-precious metal catalysts for large-scale water electrolysis for hydrogen production. NiV thin film catalysts of different atomic ratios were prepared by using sing magnetron co-sputtering technology, on self-supported carbon paper electrodes with regulating the doping level when the Ni target directional current power was set to 120 W. The results show that the NiV25 sample catalyst (with the V target radiation frequency power of 25 W) exhibits an overpotential as low as 42.3 mV for the hydrogen evolution reaction in alkaline media, corresponding to a current density of 10 mA/cm2 with having a Tafel slope of 125.17 mV with outstanding stability; notably, the NiV50 sample catalyst (with the V target radiation frequency power of 50 W) can operate continuously for 100 h at the current density of 10 mA/cm2.

Key words: water electrolysis for hydrogen production, non-precious metal catalyst, hydrogen evolution reaction (HER), doping, magnetron co-sputtering
