报道四元杂多化合物Ｋ１０Ｈ３［Ｎｄ（ＳｉＭｏ７Ｗ４Ｏ３９）２］·ｘＨ２Ｏ（简写为Ｎｄ（ＳｉＭｏ７Ｗ４）２１３－）聚吡咯（ＰＰｙ）膜修饰电极的制备及其电化学性能．该电极保持了四元杂多化合物的电化学活性和电催化性能，并具有很好的稳定性，在酸性水溶液中对ＮＯ－２具有明显的催化作用．Electronically conducting polypyrrole doped with heteropolyanions K 10 H 3[Nd(SiMo 7W 4) 2]·xH 2O(denoted as [Nd(SiMo 7W 4) 2] 13- )was synthesized by electrochemical polymerization. This modified electrode maintains the electrochemical and electrocatalytic properties of heteropolyanion, with having good stability and electrocatalytic activity on the reduction of nitric oxide in acidic aqueous solution.作者联系地址：哈尔滨工程大学化工系,中国科学院长春应用化学研究所Author's Address: Department of Chemical Engineering, Harbin Engineering University, Harbin 150001 Liu Baifeng Dong Shaojun Changchun Institute of Applied Chemistry, Chinese Academy of Science, Changchun 13002
