摘要
利用层接层自组装法(LbL),制备出有序且稳定的多金属氧酸盐K17[Ce(P2Mo17O61)2]多层膜.应用电化学、紫外光谱和X射线光电子能谱等方法研究该化合物的电化学性质及其膜修饰电极的电化学性质.
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.
