Synthesis and characterization of ultrathin multilayer films based on molybdenum polyoxometalate (Mo(54)).
The crown-shaped molybdenum polyoxometalate cluster Na(26)[[Na(H(2)O)(2)](6)[(micro(3) -OH)(4) (Mo(20)(V)), (Mo(34)(VI)(O)(164) (micro-CH(3)COO(4)) x 120H(2)O(Mo(54)) was synthesized and first used as a bulk modifier to fabricate a three-dimensional modified WIGE electrode by the layer-by-layer method. The (Mo(54))/PAH)(n) multilayer films have been characterized by X-ray photoelectron spectra (XPS) and atomic force microscopy (AFM). UV-vis measurements reveal regular film growth with each Mo(54) adsorption. The electrochemical method was used to characterize the modified WIGE electrode, which is important for practical applications.
