英文摘要：

The layer-by-layer assembly（LBL） is a technique for production of the films in nanometer range. The modified electrode of muhilayer films of polyoxometalate （POM） K17[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 muhilayer films. The proposed novel immobilized method exhibited a good high sensitivity for the determination of electrocatalyst, which is important for practical applications.
