Development of a visible-light-responsive rutile rod by site-selective modification of iron(III) ion on {1 1 1} exposed crystal faces

Effect of surface Fe2O3 clusters on the photocatalytic activity of TiO2 for phenol degradation in water

“…Samples prepared by impregnation of Fe(III) salts onto anatase and rutile TiO 2 , followed by washing and heating at 60-500 • C, show a decreased activity for organic degradation in water under UV light [8][9][10], but an increased activity for volatile pollutant degradation in air under either UV or visible light [11][12][13][14]. However, there have been also some reports showing that the modified TiO 2 is more active than TiO 2 in water, for dye degradation under UV or visible light [15][16][17], and for phenol degradation under UV light in the presence of H 2 O 2 [18].…”

Vapor-phase hydrothermal synthesis of rutile TiO2 nanostructured film with exposed pyramid-shaped (1 1 1) surface and superiorly photoelectrocatalytic performance

“…Recently, powder form rod-like rutile TiO 2 structures with exposed {1 1 1} top-facets and {1 1 0} side-facets have been developed, exhibiting excellent hydrogen production capability under visible light illumination [24]. Studies have indicated that the exposed {1 1 1} top-facets and {1 1 0} side-facets of rutile TiO 2 crystals can serve as oxidative and reductive sites for trapping photogenerated holes and electrons, respectively, which is favorable for inhibiting the recombination of the photogenerated carriers, improving the photocatalytic efficiency [25,26]. To employ photoelectrochemical technique for further improving photocatalytic efficiency, rutile TiO 2 nanostructured film with 100% exposed pyramid-shaped (1 1 1) surface has been fabricated onto FTO conductive glass substrate via a facile hydrothermal method by us [15][16][17].…”

Enhanced photocatalytic activity of bismuth-tungsten mixed oxides for oxidative decomposition of acetaldehyde under visible light irradiation

“…Actually, a pristine titania photocatalyst is less active for purification of indoor air, since the intensity of UV light emitted from a fluorescent light tube is very low. In this sense, development of visible-light-responsive photocatalysts with high levels of activity is still one of the research fields of photocatalyst materials [1][2][3][4][5][6][7].…”
