Kinetics and mechanism of an adsorptive displacement on polyoxotungstate modified electrodes
Abstract
dc:descriptionAn electrochemical approach has been used to switch adsorbate monolayers on a mercury surface between two competing adsorbates. The principle is that the adsorption strength of silicotungstic acid (SiW$\sb{12}$) is stronger than that of the oxidized form of 2,6-disulfonated anthraquinone (2,6-AQDS) but weaker than that of the reduced form of 2,6-AQDS. Thus, the identity of the molecules adsorbed on the electrode surface in contact with a solution of 2,6-AQDS and SiW$\sb{12}$ can be selected conveniently by the redox state of 2,6-AQDS which, in turn, is controlled by the electrode potential.
