| description | Herbicides and dyes in wastewater are considered serious water pollutants. These water pollutants have harmful effects on the ecosystem and due to this, the degradation of these pollutants is very important. In this article, titanium dioxide (TiO<sub>2</sub>) nanoparticles were synthesized by the sol–gel method and used as photocatalysts. TiO<sub>2</sub> powder was characterized by using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), and UV-Visible (UV-Vis) spectroscopy. The XRD analysis revealed the anatase phase for TiO<sub>2</sub>. The SEM investigation showed that TiO<sub>2</sub> nanoparticles exhibit highly irregular block-shaped morphology. TiO<sub>2</sub> nanoparticles degrade the organic pollutants under UV as well as sunlight. The photocatalytic activity of such prepared catalyst was carried out in solutions of bentazon herbicide (BZ) and Nile blue dye (NB) and in the mixture of these pollutants, under UV and sunlight. The degradation rate of both BZ and NB was very high in individual solutions as well as in the combination of them. The obtained results show that TiO<sub>2</sub> photocatalyst is a potential candidate for the photocatalytic degradation of dyes and herbicides under UV and sunlight. |
