Abstract
The exploitation of the petroleum fields generates a large amounts of wastewater of petroleum with toxicological and/or mutagenic characteristics such as benzene, toluene, phenol, xylene, and halogenated aromatic compounds. In addition, the high occurrence of dissolved gases in this matrix, such as CO2 has also aroused great concern. In order to contribute to the minimization of both problems, the present project aims to prepare and characterize photoanodes of titanium dioxide nanotubes (Ti/TiO2) and titanium dioxide nanotubes covered with graphene oxide (Ti/TiO2/GO) and applies them in photoelectrocatalytic oxidation of organic compounds in petroleum wastewater. At the same time it is intended to investigate the photoelectrocatalytic reduction of dissolved CO2 in photocathode titanium coated with titanium dioxide and copper oxide II (Ti/TiO2/CuO), aiming to form products with high energy and commercial interests.
