| 摘 要： | 本文采用层层自组装法制备包含杂多酸SiW_(12)O_(40)~(4-)(SiW_(12))和聚合物阳离子聚二烯丙基二甲基氯化铵(PDDA)的多层膜修饰电极,并用循环伏安法研究其对BrO_3~-和NO_2~-体系还原的电催化性能.结果表明:SiW_(12)修饰电极对BrO_3~-和N_2O~-的还原具有明显的电催化作用.催化电流随修饰层数的增加而明显增加.

| Abstract: | A new modified electrode was fabricated by layer-by-layer assembly of multilayer films composed of heteropolyanion(SiW12) and cationic polymer poly(diallyldimethylammonium chloride).The reduction electrocatalytic responses of BrO-3 and NO-2 on the modified electrode have been investigated.The result shows that the SiW12-containing multilayer films exhibit remarkable electrocatalytic activities for the reduction of BrO-3 and NO-2.The electrocatalytic effects are enhanced with the increasing layer numbers. |
