| Abstract | ||
| Titanium dioxide (TiO2) nanoparticles have been synthesized by sol gel method. The synthesized nanoparticles followed by calcinations at different temperatures in the range 200-800°C for 2 hours. Both the evolution of the crystal size and nature of the phases were studied as a function of annealing temperatures. These materials display a good thermal stability up to 400°C, in term of crystal size, and up to 600°C, regarding the crystalline phase. The phase purity and crystallite size of as grown TiO2 particles were characterized via X-ray diffraction (XRD). The characterized results indicated that the synthesized TiO2 powders had a pure two phases anatase and rutile structures and the average particle sizes were about 5-53 nm. The synthesized TiO2 nanoparticles exhibited 1.0053% time higher photocatalytic activity for Bismarck Brown R than that of commercial Hombikate (UV100) . | ||
