| 摘 要： | 研究了双重离子注入Ｗ＾＋／Ｎｉ＾＋，Ｗ＾＋／Ｍｏ＾＋及溅射Ｆｅ后再单离子注入Ｃｏ＾＋或Ｗ＾＋等离子束修饰的钛电极在１ＮＨ２ＳＯ４中的析氢电催化性能，结果表明：与纯钛电极相比，离子束修饰电极的催化析氢活性得到显著改善，其中，注Ｗ＾＋／Ｎｉ＾＋电极的析氢过电位降低３００ｍＶ，用ＸＰＳ和ＡＥＳ能谱分析了离子束修饰电极的表面元素及相结构，讨论了修饰电极催化所氢机理。

| Abstract: | The electrochemical behavior of Ti electrodes modified by four kinds of ion beam was investigated in 1N H 2SO 4.Ion implantation and ion sputter were adopted.The ions of beam include active elements for hydrogen evolution such as W,Ni and Fe.Compared with pure Ti,lower hydrogen overpotential was presented on these electrodes,of which,Ti electrode implanted with the W +/Ni + ions decreased overpotential by 300 mV.The mechanism of improving hydrogen evolution activity was discussed. |
