以硫代硫酸钠为硫源，磺基水杨酸为添加剂，在典型的瓦茨镀液中电沉积镍-硫(Ni-S)金属间化合物膜电极，用于碱性析氢反应。X射线衍射分析表明，沉积的Ni-S膜电极具有良好的形貌特征，由金属间化合物相结构和非晶相结构组成。与非晶相结构的Ni-S膜电极相比，金属间化合物膜电极对碱性溶液中的析氢反应具有更高的催化活性，即使是商品镍网或Ni/RuO2复合电极也是如此。
Tailoring of nickel–sulfur (Ni–S) intermetallic compound film electrodes for hydrogen evolution reaction in alkaline solutions was attempted by electrodeposition from a typical Watts bath containing sodium thiosulfate as sulfur source and sulfosalicylic acid as additive. The XRD analysis shows that the as-deposited Ni–S film electrode with fine morphological features comprised of intermetallic compound phase structure and amorphous phase structure. The intermetallic compound film electrodes generate a higher catalytic activity for the hydrogen evolution reaction in alkaline solution in comparison with Ni–S film electrodes comprised of amorphous phase structures, even with commercial Ni mesh or Ni/RuO2composite electrode.
