SYNTHESIS AND CHARACTERIZATION OF TIO2 NANOPARTICLES.

Nanocrystalline semiconductor metal oxides have achieved great importance in world today. They may be defined as metal oxides with crystal size between 1 and 100 nm. TiO2 nanoparticles have attracted significant interest of material scientists and physicists due to their special properties and have attained great importance in several technological applications such as photocatalysis, sensors, solar cells and memory devices. The TiO2 nanoparticles have excellent antimicrobial activity against broadened spectrum of bacterial strains. In the present research work synthesis of TiO2 nanoparticles has been carried on by Wet chemical method. The characterization of particles is carried out by XRD, TEM and SEM techniques. The stability of the nanoparticles is determined by TGA analysis. The importance and applications of these nanoparticles are presented and discussed in detail.
