Abstract:

The hydrothermal method was used to make the anatase phase of TiO2 nanoparticles, TiO2/La2O3 and TiO2/Al2O3 composites. FTIR spectroscopy, X-ray diffraction (XRD), UV–Vis absorption spectroscopy and scanning electron microscopy (SEM) were used to investigate the crystal structure, shape, and optical characteristics of TiO2, TiO2/La2O3 and TiO2/Al2O3 nanomaterials. The photocatalytic studies were comparatively analyzed by degrading the textile dyes methylene blue (MB) and crystal violet (CV). The degradation process was carried out in both UV light and visible light irradiation. The efficiency achieved by TiO2, TiO2/La2O3 and TiO2/Al2O3 was 87, 95, 45% and 80, 92, 29%, respectively, for MB and CV dye under UV light while under visible light it is 34, 27, 84%, and 29, 24, 81%, respectively, for MB and CV dye.
