Electrochemical properties of the [SiW10O36(M2O2

Abstract

This paper deals with the electrochemical properties of three iso-structural compounds of general formula [SiW 10 O 36 (M 2 O 2 E 2)] 6− (M = Mo or W; E = S or O). A first part is focused on their electrochemical behaviors in aqueous medium. A second part concerns the electrocatalytic properties of these compounds in aqueous medium and the preparation of modified glassy carbon electrodes through a layer-by-layer methodology. This method allowed preparing a multilayer system, which was applied to the electroanalysis of iodate anions in aqueous medium with a limit detection of 6.2 µM.
