Nanotechnology offers potential benefits to almost all industries and products. Titanium oxide (TiO2) nanoparticles exhibit unique physical and chemical properties which makes Titanium oxide suitable for various applications. In this work Titanium Dioxide nano particles were synthesized using a wet chemical method. The biopolymer chitosan was used as the precursor for the reaction. Synthesized nano particles were characterized using XRD, SEM, FTIR and spectroscopy. XRD was used to study the crystalline phase and size of TiO2 nano particles. Titanium Dioxide (TiO2) prepared by precipitation method showed rutile form with lower particle size at the calcination temperature 1000 0C. The X-ray diffraction and FTIR results indicate that the synthesized nanoparticles have only the rutile structure without the presence of any other phase impurities. SEM morphologies showed that TiO2 prepared by wet chemical synthesis gave spherical shaped nanoparticles of rutile TiO2. The size of the obtained nano particles comes under the range of 12 to 24 nm.
