摘要/Abstract

摘要：

通过静电层层自组装方法在预修饰聚二烯丙基二甲基氯化铵的电极基片上制备了Dawson型磷钼钒杂多酸/聚酰胺-胺多层复合膜. 用X射线光电子能谱、紫外-可见光谱、循环伏安法和原子力显微镜分析表征了多层复合膜的形成过程; 用循环伏安法表征了该复合膜修饰电极的电化学性能, 研究结果表明, 该复合膜修饰的电极稳定性好, 对亚硝酸盐、溴酸盐的还原以及抗坏血酸的氧化具有良好的催化活性.

Abstract:

Dawson-type molybdovanadophosphate was synthesized and then used for fabricating organic-inorganic multilayer films with a generation-4 poly(amidoamine) dendrimer as an organic spacer on electrode substrate. The multilayer films were characterized by XPS, UV-Vis, CV and AFM. The results show that the multilayer films grow gradually and uniformly, and four redox processes are observed in CV, the formal potentials of the composite films are shifted linearly to negative position at higher pH. The multilayer films electrode is stable and show good electrocatalytic activity toward the reduction of NO₂^-, BrO₃^- and the oxidation of ascorbic acid. The results show a convenient method to obtain the multilayer composite films which have potential applications in the field of electrochemical biosensors and multifunctioanal electrocatlytic materials.

Key words: Dawson structure molybdovanadophosphate; Poly(amidoamine); Multilayer film; Electrocatalysis
