“…Furthermore, the TiO 2 film sputtered at 700 C still showed diffraction of anatase, which means that a phase transfer from anatase to rutile did not occur to any significant extent at a temperature of 700 °C in situ during the sputtering process. These results are consistent with those reported by Hou et al [16]. smaller than those on the Ti mesh, although their roughness was quite similar, which was rougher than the amorphous film deposited at room temperature.…”

Two types of immobilized TiO 2 films with nanostructure, TiO 2 /ITO conductive glass and TiO 2 /Ti mesh, were prepared by a radio frequency magnetron sputtering technique, in which a titanium (Ti) target was sputtered in a gaseous mixture of argon and oxygen.The TiO 2 films were characterized by X-ray diffraction, AFM microscopy, SEM microscopy and photoelectrochemical measurements. Their photocatalytic (PC) activity, photoelectrocatalytic (PEC) activity and electrochemical (EC) activity were evaluated in the degradation of 2,4,6-trichlorophenol (TCP) in aqueous solution. The experiments confirmed that the TiO 2 films sputtered at 2.0 Pa had relatively high PC activity due to more active sites formed on the surface of TiO 2 films. The experiments demonstrated that the PEC activity of the TiO 2 /Ti mesh was better than that of TiO 2 /ITO, resulting from less impedance between the TiO 2 film and Ti mesh. Furthermore, the experiments also demonstrated that at a higher anodic potential, the TiO 2 /Ti mesh exhibited not only a PEC reaction but also an EC oxidation reaction at the backed Ti mesh in the degradation of TCP. This study concludes that the sputtered TiO 2 /Ti mesh is an effective photoelectrode for achieving an enhanced TCP degradation in such a PEC reaction system.

It has been reported that anatase is more photoactive than rutile [1,109,150,151]; however, it has also been reported that synergistic effects of mixed phases of anatase and rutile enhances the photoactivity of the photocatalyst [152][153][154][155].…”

This literature research, although not exhaustive, gives perspective to solar-driven photocatalysis, such as solar photo-Fenton and TiO 2 solar photocatalysis, reported in the literature for the degradation of aqueous organic pollutants. Parameters that influence the degradation and mineralization of organics like catalyst preparation, type and load of catalyst, catalyst phase, pH, applied potential, and type of organic pollutant are addressed. Such parameters may also affect the photoactivity of the catalysts used in the studied solar processes. Solar irradiation is a renewable, abundant, and pollution-free energy source for low-cost commercial applications. Therefore, these solar processes represent an environmentally friendly alternative mainly because the use of electricity can be decreased/avoided.

“…This fact stems from a number of its advantages like, e.g., high transparency, high stability (thermal, chemi− cal and mechanical) or photocatalytic activity [1][2][3]. The properties of titanium dioxide can be modified by the chan− ge of deposition process parameters [2,4], doping [5,6], or by the post−process treatment (e.g., annealing) [7,8]. With regards to the doping process, it is possible to obtain in this way coatings with desired structural, optical and electrical properties.…”
