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130 mV,具有很好的析氢反应活性。
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.
