The fundamental process in electro-chemical reactions is the transfer ofelectrons between the electrode sur-face and molecules in the inter-facial region (either in solution orimmobilized at the electrode sur-face). The kinetics of this heteroge-neous process can be significantlyaffected by the microstructure androughness of the electrode surface,the blocking of active sites on theelectrode surface by adsorbed mate-rials, and the nature of the func-tional groups ( , oxides) presenton the surface (1, 2). Therefore,there has been considerable effortdevoted to finding methods that re-move adsorbed species from theelectrode and produce an electrodesurface that generates reproducibleresults.
these electrodes (12). Specifically, the current responses measured us-ing cyclic voltammetry were com-pared with those calculated …
