Singh, Vasundhara materials science TiO 2 nanoparticles p. 1-20 We report a low cost and environment friendly solvent system to synthesize TiO 2nanoparticles using acidic deep eutectic solvent, choline chloride / p-toluene sulphonic acid as templating and hydrolyzing agent via sol-gel method. The effect of varying concentration of deep eutectic solvent has been investigated on the important physico-chemical characteristics of as-synthesized TiO2 such as phase, morphology, particle size, surface area and band gap energy. A detailed characterization of the obtainednanomaterials has been performed using various techniques, including X-ray diffraction (XRD), Scanning electron microscopy (SEM), Brunauer- Emmett- Tellar(BET) surface area, Raman and Ultraviolet-visible absorption spectroscopy. The spherical shaped TiO2nanoparticles was found to be biphasic having two phases: anatase and rutile with a crystallite size in the range of 5.6-6.8 nm. These spherical shaped nanoparticles assembled together to form coral-like morphology. The effect of calcination temperature on synthesized products was studied by heating at 750oC. The photocatalytic activity of the prepared TiO2materials has been evaluated by the photo-discoloration of an aqueous methyl orange dye solution (20 ppm) under UV light irradiation. The results indicate that photocatalytic efficiency of anatase-rutile mixture in sample DES-3 is higher (98% within 3h) than commercially available Degussa 2017-08-23T09:31:39Z 2017-08-23T09:31:39Z 2017 Article 2468-2284 http://repository.vnu.edu.vn/handle/VNU_123/58050 other application/pdf H. : ĐHQGHN |
