摘　　要：用电沉积法在Raney Ni基体上制备了多孔基Ni-Sn合金电极。电化学测试结果表明，Raney Ni基Ni—Sn合金电极的催化性能要好于光镍基Ni—Sn合金电极和Raney Ni电极。计算了电极的电极反应动力学参数，解释了各种电极在不同电流密度区活性不同的原因，电极的微观形貌用SEM进行表征。恒电流电解表明，多孔基Ni—Sn合金电极具有更高的活性和稳定性。Porous Ni-Sn alloys were prepared on the base of Raney Ni by electrodeposition method. The tested results on the electrochemical properties showed that Ni-Sn alloy electrode with Raney Ni base electrochemical activity was much higher than Ni-Sn alloy electrode with Ni base and Raney Ni electrodes. The corresponding electrode kinetic parameters were obtained, and then it explained why different alloy electrodes had different activity in different current density area. The micrographs of electrode surface were investigated by SEM. The high electrochemical stability was determined by constant-current electrolysis.
