Synthesis of High‐Thermal Stable Titanium Dioxide Nanoparticles

Nanosized crystals of anatase phase TiO 2 with high‐thermal stability was synthesized in the range of 15–17 nm via sol‐gel method using titanium n‐butoxide precursor. Synthesize was done at two different temperatures, that is, 200 and 300 ∘ C and the final products were calcined at 400 ∘ 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 ∘ C was heated up to 800, 850, and 900 ∘ C, the XRD results showed that the synthesized anatase phase was stable up to 850 ∘ C. Photocatalytic activity of the prepared samples showed that the fluorescien degradation followed a pseudo‐first‐order kinetic.
