Titanium Dioxide: Synthesis and Characterization

Nanotechnology is one of the extensively high advanced technologies of the world and emerging in haste with its entire span and has a diversified use. Titanium dioxide (TiO2) has been extensively studied as a photocatalyst in nanotechnology for different applications such as water and air remedy, because of its relatively high photocatalytic activity, robust chemical stability, relatively low production costs, and non toxicity. Nano-structured TiO2 was synthesized using sol-gel method with and without presence of nano porous polymer . Photocatalytic efficiency of the samples have been characterized by several techniques (SEM, EDS, UV– Spectroscopy and XRD). This photocatalytic process might be effective to remove this color and minimize the cost of an effluent treatment plant.
