Spectroscopic, Photoconductivity, and Photocatalytic Studies of TiO2 Colloids: Naked and with the Lattice Doped with Cr3+, Fe3+, and V5+ Cations

Heat Treatment in Molecular Precursor Method for Fabricating Metal Oxide Thin Films

“…Many researchers study the fabrication and photoreactivity of Vis-responsive thin films by physical and/or chemical modification of anatase films because of the importance of Visphotoreactive materials [53][54][55][56][57][58][59][60][61]. However, there is little information on the enhancement of UV sensitivity of Vis-responsive anatase films.…”

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14] Mid-gap photoactivity is usually associated with donor-or acceptor-type photoionization (or charge-transfer) transitions of the added impurity ions. Such transitions can generate one band-like charge carrier (either a conduction-band electron or a valence-band hole) by formal charge transfer from or to the impurity.…”

Preparation and characterisation of AgIn(WO4)2photocatalyst with high photoreduction activity

“…From the viewpoint of solar-energy utilisation, some methods have been developed in recent years. One method is doping various metal ions or nonmetal ions, such as Co, V, Cr [7][8][9][10] or N, S, C [11][12][13][14][15][16] into TiO 2 ; another important way is to synthesise a novel non-TiO 2 -based photocatalyst, such as NaTaO 3 [17], In 2 S 3 [18,19] etc. Although, these photocatalysts showed superior performance in some aspects, the quantum efficiency is still low.…”
