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.
