Titanium dioxide shows outstanding chemical stability, high refractive index photochemical activity and high dielectric constant, which are expected to play important roles in many fields. In recent years, there has been increasing interest in the application of TiO2 nanoparticles for pigments,catalysts and supports, ceramics, gas sensors, inorganic membranes,waste water purification and solar energy conversion. The uses and performances for a given application are, however, strongly influenced by the crystalline structure, the morphology and the size of the particles. Therefore, in this book...

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...
