摘　　要：从电极析氢反应的动力学参数、真实交换电流密度、标准活化自由能及电化学稳定性等方面研究了 ( Ni-Mo) -WC电极在碱性介质中的电催化析氢性能 .实验结果表明 ,复合电极的电催化析氢性能高于基质合金电极 ,这主要归因于比表面积的增加 .To study the activity for electrocatalytic hydrogen evolution of (Ni-Mo)-WC composite electrode in alkaline medium, the kinetic parameter, the true exchange current density and the standard free energy of activity for the Hydrogen Evolution Reaction(HER) of the composite electrodes were measured. In addition, the electrochemical stability of them was investigated. The experiment results show that the activity for HER of the composite electrodes are higher than that of substrate metal electrode, the higher activity was mainly due to the increase in surface area of the electrodes.
