| 摘 要： | 采用电沉积法在镍网上制备Ni-S合金，在固定的溶液组成、电镀的电流密度和温度的条件下，研究电沉积时间对电极析氢过电位的影响。试验结果表明，与未镀合金的电极相比，Ni-S合金电极的析氢过电位可降低130mV，具有很好的析氢反应活性。

| Abstract: | Nickel-sulfur alloy based on nickel net was obtained by electro-deposition.On the given solution composition and electro-deposition current and temperature, the influence of the electro-deposition time on the hydrogen evolution reaction overpotentials of the Ni-S alloy was analyzed.The results of experiment showed that the hydrogen evolution reaction overpotentials of the Ni-S alloy reduced 130 mV compared with those of the cathode that wasn't electrodeposited.The Ni-S alloy performs an excellent electrocatalytic property for the hydrogen evolution reaction. |

| Keywords: | nickel-sulfur alloy water electrolysis hydrogen evolution reaction overpotential |
