Abstract: This review reports the major characteristics associated with titanium–dioxide nanoparticles for different methodology. Titanium dioxide has drawn attention worldwide for large scale manufacturing due to its properties along with nontoxic behavior for various applications. Titanium dioxide is considered as suitable for materials for pollution degradation and helps to promote the rate of photosynthesis. Structural properties were discussed with help of X-ray diffraction that helps to investigate physical characteristics. The estimated crystallite size found to be increase with increase in temperature. Morphological analysis was done with the help of scanning electron microscopy and transmission electron microscopy. The morphological behavior shows the formation of homogeneous spherical nanoparticles and agglomeration obtained for sample calcinated at higher temperature.
