ResumoThe photocatalytic degradation of textile dyes using metallic oxides has been extensively studied due to the remarkable results. This promising approach offers a more sustainable alternative for treating textile effluents contaminated with dyes and other chemicals, intending to mitigate the environmental impact caused by the textile industry. In this context, this study aimed to investigate the degradation of different classes of synthetic dyes used in industry through the heterogeneous photocatalysis process. For this purpose, TiO2 P25 dispersed in an aqueous dye medium exposed to an isolated source of artificial UV light was used. The significance of this research lies in understanding photodegradation phenomena and studying heterogeneous catalysis mechanisms applied to the degradation of textile dyes. Furthermore, the importance of sustainability in the textile industry is highlighted, emphasizing the need for new solutions to reduce waste emissions. This study contributes significantly to understanding the degradation of textile dyes through photodegradation, providing detailed information on the reaction processes and key factors influencing the efficiency of TiO2-catalyzed degradation. The results demonstrate real application potential and support sustainable strategies for treating textile effluents, aiming to reduce the environmental impact caused by dyes.
