Preparation and Electrochemical and Electrocatalytic Properties of Nanocomposite Multilayer Film Based on a Keggin-Type Phosphomolybdate
An electrostatically self-assembled multilayer film has successfully been prepared on quartz or indium-tin-oxide substrates by alternating adsorption of a Keggin-type phosphomolybdate H3PMo12O40 (PMo12) and 1,10-diaminodecane (1,10-DAD). The
formation of (PMo12/1,10-DAD)
n
film was investigated by ultraviolet (UV) spectroscopy. The UV spectra showed that the deposition of the films was uniform and reproducible. The cyclic voltammetry on the PMo12-based multilayer film indicated that the PMo12
anions in the film undergo rapid four 2e−/2H+ redox processes, and electrocatalytically active towards the reduction of bromate.
