SYNTHESIS, CHARACTERIZATION AND ANTIBACTERIAL ACTIVITY OF TITANIUM DIOXIDE (TIO2) NANOPARTICLES.

Abstract

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
