Resumo: The electrochemical oxidation of toluene in aqueous-acid medium was studied on monolithic and reticulated glassy carbon electrodes using cyclic voltammetry. The oxidation potential was 1.7 V for both electrodes. However, the normalized oxidation currents were higher on reticulated glassy carbon, showing more catalytic activity than on the monolithic glassy carbon. To normalize the obtained anodic current values, a method for the determination of the electrodes effective area was used, which consists in the underpotential deposition of a copper monolayer.
