“…Our experimental results have confirmed the formation of one-dimensional elongated nanostructures obtained by alkalic hydrothermal treatment of TiO 2 powder without organic additives [5,6]. However, the interlayer distances in structures produced by processing of TiO 2 powder with chitosan are significantly increased from $0.7 (without organic additives) to $1.2 nm (with chitosan).…”

One-dimensional TiO 2 -based nanostructures with modified surface have been produced by alkaline hydrothermal treatment of TiO 2 and CoTiO 3 powders in the presence of bioactive natural polymer-chitosan-as the organic reagent. Nanostructures are characterized by multilayer morphology. However, characteristic interlayer distances are significantly higher than in those produced without chitosan. Moreover, thin bioorganic layers are observed on the surface of elongated structures produced by processing of TiO 2 powder. Quite different surfaces with numerous Co-containing agglomerates of chitosan derivatives are detected when CoTiO 3 powder is processed. After vacuum treatment at 600 C and higher, Co-containing elongated nanostructures demonstrate the abnormal high ferromagnetic properties.

“…Sengele et al obtained Ta-doped TiO 2 via a sol-gel route and found that the Ta doping could induce significant modifications on the structural, morphological, surface, electronic, and optical properties of TiO 2 [203]. Total diethylsulfide elimination could be reached for 100 min under continuous contaminant flux before deactivation and the conversion maintained to 80% of degradation after 200 min, which was higher than undoped TiO 2 catalysts [204][205][206][207][208].…”

As a kind of highly effective, low-cost, and stable photocatalysts, TiO 2 has received substantial public and scientific attention. However, it can only be activated under ultraviolet light irradiation due to its wide bandgap, high recombination, and weak separation efficiency of carriers. Doping is an effective method to extend the light absorption to the visible light region. In this chapter, we will address the importance of doping, different doping modes, preparation method, and photocatalytic mechanism in TiO 2 photocatalysts. Thereafter, we will concentrate on Ti 3+ self-doping, nonmetal doping, metal doping, and codoping. Examples of progress can be given for each one of these four doping modes. The influencing factors of preparation method and doping modes on photocatalytic performance (spectrum response, carrier transport, interfacial electron transfer reaction, surface active sites, etc.) are summed up. The main objective is to study the photocatalytic processes, to elucidate the mechanistic models for a better understanding the photocatalytic reactions, and to find a method of enhancing photocatalytic activities.

In this research, we have synthesized pure monolithic titania using nanocasting technology with hydrophilic urea formaldehyde resin as a template. Powder X-ray diffraction and scanning electron microscopy results have shown that the titania monolith has interwoven skeletons and textural pores, and the crystalline is anatase. The prepared titania monolith was employed as a photocatalyst under UV light by using methyl orange (MO) as a target. Photocatalytic results showed that concentration of the MO solution decreased nearly 87% after 60 min of degradation, and after four repeated cycles of reuse, photocatalytic activity of the regenerated catalyst showed no significant change.
