چکیده

Titanium dioxide (TiO₂)nanoparticles have been frequently employed in the environmental treatment and purification purposes as a cheap and highly efficient photocatalyst. A photocatalyst can facilitate the breakdown and removal of a variety of environmental pollutants at room temperature. TiO₂ photocatalyst is the best candidatebecause of its strong oxidized ability, non-toxicity and longthermal photostability. The TiO₂ is also importantand need deep studies because it can be used as self-cleaningand anti-fogging glass in future.In this paper, TiO₂ nanoparticles were synthesized by liquid phase method. The samples were characterized by x-ray diffraction (XRD) and transmission electron microscopy (TEM) analyses after heat treatments. The XRD results show the sharp picks after annealing process. The TEM results reveal that the size of nanoparticles is in the range of 20-40 nm in diameter. Raman scattering pattern of the TiO₂ nanoparticles confirm the TEM analysis and indicate the anatase phase
