Abstract

The novel multilayer nano-composite films constructed from copper mono-substituted polyoxometalates ([PCu(H₂O)Mo₁₁O₃₉]^5－) and a generation-4 poly(amidoamine) dendrimer (PAMAM) were fabricated on ITO conductive glass and glassy carbon electrode by electrochemical scanning method. The composition of the multilayer films was characterized by X-ray photoelectron spectra. Atomic force microscopy presented an uniform surface morphology of the multilayer films. The multilayer films were grown gradually and uniformly in the synthesis process as monitored by cyclic voltammetry. The electrochemical properties of [PCu(H₂O)Mo₁₁O₃₉]^5－ in the films were different from those in homogeneous aqueous solution. The multilayer films showed good electrocatalytic activity towards the reduction of and oxidation of ascorbic acid (AA).

Key words: copper-substituted polyoxometalate, PAMAM, multilayer films, electrocatalysis
