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...

Photo catalytic degradation is the degradation of photodegradable molecules by absorption of photons, particularly those wavelengths found in sunlight such as infrared radiation, visible light and ultraviolet light in presence of catalyst. Removal and degradation of organic dyes are matter of considerable interest, because of potential toxicity of dyes and theirs visibility in surface waters. A wide range of methods have been developed, amongst which the heterogeneous photo catalysis involving titanium dioxide (TiO2) appears to be the most promising technology. Here we express the designing...
