Abstract: Contamination of water by industrial waste is a major challenge for modern society, as many substances released into effluents, such as methylene blue dye (C16H18ClN3S), are highly toxic and impair the performance of vital activities of living organisms. Due to this impasse, researches have been engaged in the search for sustainable technologies for the degradation of these harmful chemical species, with emphasis on the use of biomasses, due to their low cost and their porous structures that give them good adsorptive efficiency, has also gained space. the use of composites, materials formed by joining characteristics of pioneer species in order to improve processes, in this case, the degradation of pollutants. Another alternative is heterogeneous photocatalysis, an Advanced Oxidative Process.This work aims to formulate pequi bark composites (biomass) supported with copper nitrate and submit them to heterogeneous photocatalysis to degrade methylene blue. After the photocatalytic tests the materials were characterized by XRD, 100% of degradation was obtained for the catalyst made with the mixture of TiO2 and biomass and 92.14% for the one formed by the mixture of the same substances plus 10% of copper these data can be considered promising, given that the composite TiO2 and copper-free biomass obtained more efficient results than commercial TiO2, which is the material most commonly used in photocatalysis today.
