Book Description
During the past decade, research and development in the area of synthesis and applications of different nanostructured titanium dioxide have become tremendous. This book briefly describes properties, production, modification and applications of nanostructured titanium dioxide focusing in particular on photocatalytic activity. The physicochemical properties of nanostructured titanium dioxide are highlighted and the links between properties and applications are emphasized. The preparation of TiO2 nanomaterials, including nanoparticles, nanorods, nanowires, nanosheets, nanofibers, and nanotubes are primarily categorized by their preparation method (sol-gel and hydrothermal processes). Examples of early applications of nanostructured titanium dioxide in dye-sensitized solar cells, hydrogen production and storage, sensors, rechargeable batteries, electrocatalysis, self-cleaning and antibacterial surfaces and photocatalytic cancer treatment are reviewed. The review of modifications of TiO2 nanomaterials is mainly focused on the research related to the modifications of the optical properties of TiO2 nanomaterials, since many applications of TiO2 nanomaterials are closely related to their optical properties. Photocatalytic removal of various pollutants using pure TiO2 nanomaterials, TiO2-based nanoclays and non-metal doped nanostructured TiO2 are also discussed.

Book Description
Titanium dioxide (TiO2) has drawn considerable attention as an attractive inorganic raw material for various applications due to its inexpensiveness, nontoxic nature, stability, and excellent photocatalytic activity. Photocatalysis is one of the most promising route for sustainable chemistry of the 21st century. It can contribute to solving environmental, global energy, and chemical problems, as well as to the sustainable production of commodities in the near future. This book presents the fundamentals of photocatalysis in nanostructured TiO2 and describes the factors affecting the photocatalytic activity, design, and synthesis of various forms of nanostructured TiO2. It highlights the use of ion-doping and inert-atmosphere annealing to extend the light-absorption range of photocatalysts and reduce recombination between electrons and holes. It discusses numerous applications in the fields of energy and environment, such as water purification, gas sensing, storage and delivery, and energy generation. The book is an invaluable resource and useful guide for a broad readership in various fields of catalysis, materials science, environment, and energy.

Book Description
Nanocrystalline titanium dioxide (TiO2), a wide band-gap semiconductor, is synthesized by a sol-gel method for studies of its photocatalytic activity. In this work, surface modification of TiO2 utilizing various species is performed. The surface modifications are performed on both pure and doped TiO2. It is shown that surface modifications affect the phase transition temperature of TiO2. Band gap energy modifications, via dopants, in combination with surface absorbed species have been shown to affect the photocatalytic activity of TiO2. Surface adsorbed species must be inert to redox reactions in order remain bound to the surface, yet facilitate charge transport from the TiO2 bulk into a species on the surface. Typically dye sensitizers are anchored to semiconductor oxide surfaces via carboxylates. The polarization at the carboxylate-oxide interface junction may interfere with the charge injection process. Here, the use of anchors containing species of different polarities (phosphates, sulfates, silicates, etc.) at the interface junction is analyzed for improvements in the charge injection process. This charge injection process is measured by observing the extent in which methylene blue is degraded. In this work, characterization is performed by a variety of microscopic and spectroscopic techniques.
