Voltammetric behaviour of single particles of silver chalcogenides in the micrometric range. Comparison with measurements at modified carbon paste electrodes

Résumé

Voltammetry with single particles of Ag2Se, Ag2Te and Ag2S of a size ranging from 10 to 100 μm and put on an electrolyte soaked separator, has been performed and compared with previous measurements at carbon paste electrodes in concentrated sulphuric acid and NaClO4 medium. The results confirm those obtained with traditional electrodes and point out the disturbing role of the binder. Moreover, the fact that chalcogenide particles behave as ultramicroelectrodes, except that cyclic voltammograms display peaks at extremely low scan rates, has allowed studies in the absence of deliberately added supporting electrolyte.
