摘　　要：本文研究了注入镍离子的钛电极在5％NaCl-0.01mol·dm^(-3)HCl溶液中H^+的阴极还原反应.采用电化学方法及AES,XPS,TEM等对电极的电化学性质、表面元素分布、化学价态及形貌等进行了分析.发现该类电极对H^+的还原反应具有比纯Ti高得多的催化活性.In the present study, Ni ion implanted Ticathode was used to research for the oathodic reduction of H^+ in 5% NaCl-0.01mol·dm^(-2) HCl solution. The electrocatalyic property, the distribution of the elements, chemical valencies and the surface morphology of the electrode were detemined by electrochemical method and AES, XPS, TEM, etc. techniques. It was found that this electrode showed much higher catalytic activity than the pure Ti did for the reduction of H^+.
