Nanosized crystals of anatase phase TiO2 with high-thermal stability was synthesized in the range of 15-17nm via sol-gel method using titanium n-butoxide precursor. Synthesize was done at two different temperatures, that is, 200 and 300 degrees C and the final products were calcined at 400 degrees C. The final products were characterized by N-2 adsorption, X-ray diffraction, FT-IR, and TEM and tested in a photoreactor using fluorescien as model molecule. For thermal stability investigation, the sample prepared at 300 degrees C was heated up to 800, 850, and 900 degrees C, the XRD results showed that the synthesized anatase phase was stable up to 850 degrees C. Photocatalytic activity of the prepared samples showed that the fluorescien degradation followed a pseudo-first-order kinetic. Copyright (c) 2008 M. Rashidzadeh.
