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...
