Abstract:

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) 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 multilayer films. The proposed novel immobilized method exhibited a good high sensitivity for the determination of electrocatalyst, which is important for practical applications.

Key words: Polyoxometalate;  Glassy carbon electrode(GCE);  Multilayer film;  Layer-by-layer self-assembly;  Electrochemical behavior
