Abstract

The use of materials consisting of carbon or carbonaceous materials in environmental studies is known in the literature. Some studies aim at the chemical or physical activation of these materials for specific applications, from the improvement in the adsorption of contaminants to the preparation of carbon electrodes for studies of the oxygen reduction reaction. However, the acquisition of carbon powder for laboratory studies is not trivial due to the small number of Brazilian suppliers and the supply of the product is always in large quantities, higher than necessary for academic studies. In this context, the present project aims to synthesize activated carbon from the calcination of wood residues, with subsequent chemical activation and application as electrodes in the RRO study in aqueous acid medium, comparing the electrochemical activity of carbon sintered with commercial carbon materials known in the literature.
