| 摘 要： | 在（Ｎｉ－Ｓｎ）／Ｐｂ合金修饰电极中添加某些金属氧化物进行改性，用于电解合成Ｌ－半胱氨酸反应。结果证明，添加ＷＯ３后电极反应活性大大加强，反应同期转化率有较大提高，选择性也有所提高，添加稀土金属氧化物能有效降低反应阴极过电位，使反应选择性有所提高，但是电极稳定性还有待改善。

| Abstract: | The (Ni Sn)/Pb electrode was modified with some metal oxides and applied to the electrosynthesis of L cysteine. It was found that the performance of electrode modified with WO 3 was enhanced greatly; the conversion and selectivity of reaction were increased somewhat; the electrode modified with rare earth metal oxide could lower the cathode potential effectively, and the selectivity of reaction was enhanced obviously, but the electrode was less stable. |
