The layer-by-layer assembly (LBL) is a technique for production of the films in nanometer range. The modified electrode of multilayer films of polyoxometalate (POM) K-17[Ce(P2Mo17O61)(2)] and polyelectrolyte by the layer-by-layer assembly were prepared and investigated. The stable multilayer films were assembled by alternate adsorption of negatively charged POM and positively charged polyelectrolytes from their aqueous dispersions. UV-Vis spectroscopy and cyclic voltammetry were used to monitor the regular growth of the multilayer films. The proposed novel immobilized method exhibited a good high sensitivity for the determination of electrocatalyst, which is important for practical applications.
