Abstract The in-situ generation of hydrogen peroxide in the electro-Fenton process is paramount. For this reason, in this research the electrocatalytic activity of three carbon materials was evaluated in the reaction of oxygen reduction via two electrons. Furthermore, in order to eliminate the use of iron salts in solution (homogeneous process), the iron was electrodeposited on the surface of the carbon material and was applied in a heterogeneous electro-Fenton process for the degradation of methyl orange dye. The largest amount of generated H2O2 was achieved with the Carbon Felt (CF) electrode (460 mg L−1) without iron after 60 minutes. The electrodes with electrodeposited iron were characterized by SEM and EDS, which showed that the surface of the Carbon Sponge (CS) electrode had the largest amount of iron (23.84 %). However, the CF electrode showed a greater and faster degradation of the dye (98 %) after 30 minutes of treatment. The CF material was the best and most-viable choice of material compared to the CS and Carbon Cloth (CC) for industrial application in electro-Fenton processes, due to its greater catalytic activity in the production of H2O2, uniform distribution of iron, more efficient TOC removal and lower cost per cm2 of material.

Horseradish peroxidase (HRP) can be used for the treatment of halogenated phenolic substances. In the presence of hydrogen peroxide phenols are oxidized to form polymers which undergo partial dehalogenation. However, when immobilized, the peroxidase is subject to inactivation due to blockage of the active sites by the growing polymers and to deactivation by elevated levels of hydrogen peroxide. When HRP immobilized on a novel glass-based support incorporating titanium dioxide is subjected to UV irradiation, hydrogen peroxide is produced and the nascent polymer is removed. In this work a reactor was constructed that utilized HRP immobilized on the novel support and the in situ production of hydrogen peroxide to treat 4-bromophenol as a model substrate. The system was operated for almost 17 hours with no apparent decline in activity.
