| 摘 要： | 用复合镀法制得Ｎｉ－Ｗ－ＷＣ－ＷＯ３复合电极，在０．５ｍｏｌ／ＬＨ２ＳＯ４中的氢超电势比软钢降低２８０ｍＶ，ｉ０提高三个数量级，电极表面粗糙度为Ｎｉ电极的三倍。在３００ｍＡ／ｃｍ＾２的大电流密度下，进行的长期恒电流电解试验表明电极性能稳定。ＸＰＳ分析证明电极表面主要成分为Ｎｉ，Ｗ，ＷＣ，ＷＯ３等。

| Abstract: | The Ni-W-WC-WO_3 composite cathode was obtained by electroplating on nickel cathode substrate. Its exchange current density i_0 greatly increases and its hydrogen overvoltage greatly decreases than Ni and Fe. The surface area of Ni-W-WC-WO_3 cathode is two fold more than that of the Ni electrode. Electrolytic experiment by high current density (300 mA/cm~2) showed that the cathode had steady activity. XPS analysis indicated that the component of electrode surface are Ni,W,WC,N,WO_3 etc. |
