Аннотация
Tungsten oxides were electrochemically deposited from a metastable acidic solution of isopolytungstate on simple glassy carbon electrodes and glassy carbon electrodes coated with a film of a conductive polymer poly(3,4-ethylenedioxythiophene). It was found by the cyclic voltammetry method that the redox capacity of tungsten oxide deposits on the conductive polymer film is noticeably greater than on glassy carbon, which indirectly points to its high dispersion. The morphology of the tungsten oxide deposits was studied using scanning electron microscopy. The tungsten valence state in the composition of surface tungsten oxides was determined by the X-ray electron spectroscopy method.
