When these ID nanocrystals are deposited on a surface, typically a random direction exists for the elongating axis of each ID nanocrystal. However, if the preparation method leads to an alignment of the elongating axis in one single direction, e.g. when an ordered array is present, quasi-2E) nanostructures are present. This class of nanostructured Titania thin film may be extended to include also ordered mesoporous Titania membranes, e.g. when the pores are aligned in one single direction. 

A simple method to fabricate nanostructured titania was proposed by Wang et a/.253,254 to produce ordered Ti02 nanobowl arrays. The process starts with a... 

Research advances in the last few years have significantly progressed the possibility of developing new nanostructured Titania catalysts having controllable phase and architecture. This review is limited to quasi-1D Ti02 nanostructures, e.g. nanorods, nanowires and nanofibres, nanotubes and nanopillars.

Usually the nanotube arrays have been made from a titanium thick film or foil, in which case the resulting nanotubes rest upon an underlying Ti substrate as separated by a barrier layer. The nanotube arrays have also been fabricated from a titanium thin film sputtered onto a variety of substrates, such as silicon and fluorine doped tin oxide (FTO) coated conductive glass. This extends the possibility for preparing technical catalysts by deposing a thin Ti layer over a substrate (a foam, for example) and then inducing the formation of the nanostructured titania film by anodic oxidation. ...

A novel method of a photocatalytic lithography based on a photogeneration of Pd nanoparticles in thin films of Pd2+-doped nanostructured titania followed by an electroless nickel plating is proposed. The possibility of a generation of both negative and positive metal patterns employing TiC>2 Pd2+ photolayers is discussed in terms of a dispersity of a photoproduced Pd nanophase and its catalytic activity towards an eletroless nickel deposition. 

Very recentty, improvement in rate capability, capacity, and cycling behavior has been observed in the case of nanostructured titania, strengthening the possibility to use this oxide as a negative material for Li-ion batteries. Bruce and Lindsay have reported that the crystallite size and shape play key roles for improving the performances of the electrodes [22, 23], It also has to be noted that their investigation concerned either hydrothermal synthesized Ti02 nanotubes or anodic oxide thin...

A schematic of the PEC device is displayed in Figure 1.8, drawn after Li [44], The PEC utilised by Centi and co-workers [113,116,117] had on the cathode side a photocatalyst (nanostructured titania, 1 in Figure 1.8), which photochemically oxidised water to produce molecular oxygen, protons and electrons. Next, the H+ ions crossed the proton-exchange membrane (2 in Figure 1.8), and electrons assisted by protons enabled the...
