Book Description
Titania nanofibers were fabricated using electrospinning and characterized using SEM, XRD and TEM for morphology, chemistry and crystalline structures. The prepared titania nanofibers were approximately 20 nm in diameter and consisted of anatase phased crystalline grains having sizes of ~10 nm. Different spin dopes were prepared by varying the ratio of N, N=dimethylformamide (DME) to isopropanol (IPA). The results indicated that the precursive nanofibers and the final TiO2 nanofibers made from the spin dopes containing DMF alone or DMF/isopropanol mixture as the solvent had the common cylindrical morphology with diameters ranging from tens to hundreds of nanometers, while those made from the spin dope containing isopropanol alone as the solvent had the abnormal concave morphology with sizes/ widths ranging from sub-microns to microns. Electrospun titania nanofibers as well as a commercial titania powder were used to prepare aluminum/titania composites using friction stir processing, and the morphological structures of the composites were characterized using TEM. The interaction of the aluminum matrix with nanofibers was found to be stronger than powder in the aluminum matrix. Comparison of microhardness measurement of the titania nanofibers/aluminum composite with titania power/aluminum composite indicated that the hardness increment is higher with nanofibers than powder. The photocatalytic efficiency of electrospun titania nanofibers is compared with that of commercial titania sample (Degussa P 25) for the degradation of Rhodamine B. The degradation rate of Rhodamine B after 15 min irradiation is identical for both the catalysts.

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.
