在电沉积镍－钼合金上的析氢反应

Hydrogen Evolution Reaction on the Electrodeposited Ni-Mo Alloys

本文运用极化曲线和电化学阻抗图谱等方法，研究了含钼量不同的镀液电沉积镍铝钼金在７ｍｏｌ．Ｌ－１氢氧化钠溶液中的析氢动力学过程．实验结果表明，随着镀液钼含量的增加，镀层的析氢催化活性大大增加，其活性大大超过纯镍和纯钼电极．同时初步探索了各种沉积条件对析氢催化活性的影响．

The hydrogen evolution reaction (HER)on the Ni-Mo alloy by electrodesition in7mol/L NaOH at room timperature have been investigated using steaby-state polarizationand AC impedance techniques.Experimental results show that the activity of these electrodes increases with an increasing molybdenum content in the bath. The hydrogen overpotential of these electrodes are much lower than that observd for pure mickel and molybdenumrepectively.The effect of electrodposition conditions on the catalytic actively of HER has also been discussed.
