The high catalytic activeness of Titanium dioxide (TiO2) nanoparticles makes it one of the most important and promising semiconductor oxide material, good gas-sensitive characteristics, di-electricity, high stability, low cost, non-toxic, and its potential use in any applications. These nano-sized particles exhibit beneficent wide band for absorption of UV, which has recently been used in sunscreen applications. In the present work Sol-gel method was used to prepare titanium dioxide (TiO2) nanoparticles. The sample was characterized by powder XRay diffraction (PXRD), Energy Dispersive X-Ray analysis (EDX) and Scanning Electron Microscopy (SEM).The average particle size of the sample was calculated from PXRD peaks by Debye-Scherer's equation and size to be in nano range.The average crystallite size from sharp peak of Rutile was 22.41 nm, which was estimated by using the Scherer's formula.
