Carbon paste electrodes made from novel carbonaceous materials: Preparation and electrochemical characterization

This work describes the preparation of novel carbon paste electrodes by mixing of different carbonaceous materials with an organic binder (Nujol). All carbonaceous materials employed in this study were synthesized from the pyrolysis of different poly(furfurylalcohol)-based precursors, and will be referred here as glassy carbon (GC), template carbon (TC), porous carbon foam (CF) and porous carbon microspheres (CM). Studies on the best carbon/Nujol ratio, potential window and electrochemical reactivity were carried out for each carbonaceous material, and the results are discussed in terms of the materials structure and morphology. In order to comparison, similar electrodes were made from commercial graphite. The possibility of utilization of the different electrodes in electroanalysis and electrocatalysis is discussed.
