Voltammetry of MicroParticles in Thin Layer

Abstract : We describe a new experimental device for the characterization of electroactive microparticles and of the soluble species released during their electrochemical transformation. By using only a few microparticles, it provides, in a faster way, similar information as modified carbon paste electrodes with electrolytic binders (CPEEBs) and the sensitivity and resolution are must better. The device geometry was modelled with ferrocyanide ions and the voltammograms for ferrocene, pyrolusite and hematite were compared with the literature ones concerning CPEEBs. Finally, an alumina-supported palladium catalyst and pyrite-containing argillite were successfully characterized.
