| 中文摘要 | the preparation, structure, and electrochemical and electrocatalytical properties of a new polyoxometalate-based organic/inorganic film, composed of cetyl pyridinum 11-molybdovanadoarsenate (cpmva) molecules, have been studied. cyclic potential scanning in acetone solution led to a stable cpmva film formed on a highly oriented pyrolytic graphite (hopg) surface. x-ray photoelectron spectroscopy, scanning tunneling microscopy, and cyclic voltammetry were used for characterizing the structure and properties of the cpmva film. these studies indicated that self-aggregated clusters were formed on a freshly cleaved hopg surface, while a self-organized monolayer was formed on the precathodized hopg electrode. the cpmva film exhibited reversible redox kinetics both in acidic aqueous and in acetone solution, which showed that it could be used as a catalyst even in organic phase. the cpmva film remained stable even at ph > 7.0, and the ph dependence of the film was much smaller than that of its inorganic film (h4asmo11vo40) in aqueous solution. the cpmva film showed strong electrocatalysis on the reduction of bromate, and the catalytic currents were proportional to the square of the concentration of bromate. the new kind of polyoxometalate with good stability may have extensive promise in catalysis. |
