Transparent photocatalytic surfaces are of ever increasing importance for many applications on self-cleaning windows and tiles in everyday applications. Here, we report the formation and photocatalytic testing of a quasi-transparent thin and nanoporous titania films deposited on glass plates. Sputtered Ti thin films were anodized in fluoride-ion-containing neutral electrolytes to form optically semitransparent nanoporous films, which transformed to be completely transparent after thermal annealing. The nanoporous films were studied at different stages, such as before and after anodization, as well as after thermal annealing using scanning electron microscopy (SEM), X-ray diffraction (XRD), and UV-vis and Raman spectroscopy. It was observed that anodization at 20 V of high-temperature deposited titanium films resulted in regular nanopore films with pore diameters of 30 nm. Structural investigations on the transparent nanopore arrays reveal the presence of anatase phase TiO(2) even after annealing at 500 °C, which was confirmed by XRD and Raman spectroscopy measurements. The solar-light induced photocatalytic decomposition of stearic acid and photoconductivity characteristics of these nanoporous thin films are also presented.

“…We found in our former research [11] that the photocatalytic activity of anatase TiO 2 films depends on the atomic defect density of the films; atomic defects act as the recombination sites for photogenerated electrons and holes during the carriers diffusing to the film surface; highly photoactive TiO 2 has a small atomic defect density.…”

“…The formation of well-crystallized anatase TiO 2 on Si 3 N 4 and the hydrophobic surface of Si 3 N 4 was found to be related to the efficient photocatalytic activities of TiO 2 / Si 3 N 4 hybrid photocatalysis (Ohsaki et al 2008, Trice et al 2008). In order to improve the transmission of UV light, TiO 2 photocatalysis is further loaded onto Si 3 N 4 with the honeycomb structure having a hydrophilic surface and three-dimensional pore structure using a conventional dip-coating method (Kumar Gain et al 2006).…”

AbstractFor the past 40 years, titanium dioxide (TiO2) nanomaterials have attracted immense attention because of their potential applications in the photodegradation of organic pollutants, photocatalytic water splitting for H2 generation, and dye-sensitized solar cells. Despite the fact that the potential applications of TiO2 nanoparticles are ubiquitous, they are not problem free, examples include a large interfacial area that causes slow charge carrier transport, a wide optical band gap that leads to limited applications using solar light, and single-phase and nanoscales features that induce fast recombination of photo-reduced carriers. Therefore, this review highlights the development associated with the adsorption photocatalysis hybrid system for treating wastewater. The immobilization of TiO2 photocatalysts in metal oxide, carbon, and ceramic materials to form TiO2 hybrid systems could prevent the problem of particle recovery, adsorption capacity, and the separation process. Such hybrid systems require significant effort of optimizing the specific surface area-to-volume ratio of the supported photocatalysts with its photocatalytic activities.
