Electrochemistry of a Carbon Microfiber Adsorbed by Cobalt Nanoparticles

Abstract

The adsorption of cobalt nanoparticles on a carbon microfiber surface has been electrochemicaly detected. The redox processes observed in an electrochemical cell filled with redistilled water and equipped with the carbon fiber microelectrode modified by cobalt nanoparticles have been compared to those observed in an aqueous solution of Co²⁺ cations. The movement of the adsorbed nanoparticles has been demonstrated by the feedback capacitance-potential method.
