Synthesis and properties of nanoparticulate titanium dioxide compounds
… designed and constructed for the preparation of TiO2 nanotubes. Conditions of anodic oxidation were established to reproducibly prepare TiO2 nanotubes of average length 35-50 μm vertically orientated relative to the plain of a pure titanium metal sheet. A non-aqueous solution of ethylene glycol …

Growth of anodic alumina nanopores and titania nanotubes and their applications
… arrangements. The formation mechanism of anodic TiO2 nanotubes is proposed in this dissertation. Moreover, FIB pre-pattern guided anodization is introduced to synthesize highly ordered TiO₂ nanotubes with different morphologies. The effects of inter-tube distance and arrangement to the structure …

Enhancing the photoelectrochemical water splitting characteristics of titanium and tungsten oxide based materials via doping and sensitization
… various semiconducting photoelectrodes such as TiO2, WO3 and CuWO4 were investigated. Due to the inherent wide gap, such metal oxides absorb only ultraviolet radiation. Since ultraviolet radiation only composes of 4% of the sun's spectrum, the wide band gap results in lower charge collection and …
