Abstract
In this work, research on the electrocatalytic oxidation of organic compounds on composite electrodes containing cobalt and nanometric carbon fillers is presented. The selected organic compounds for electrolytic oxidation were methanol and urea. The obtained composite electrodes were characterized by a greater degree of surface development and larger surface coverage of redox species than those of cobalt electrodes. The composite electrodes containing nanometric carbon forms showed favorable properties in the oxidation of organic compounds. The results obtained in both the methanol and urea solutions indicated the repeatability and stability of the processes occurring on the surface of the electrodes. In addition, composite electrodes containing graphene were characterized by higher electrocatalytic activity in the oxidation of organic compounds.
