Photoassisted Degradation of Dye Pollutants. V. Self-Photosensitized Oxidative Transformation of Rhodamine B under Visible Light Irradiation in Aqueous TiO2 Dispersions
Chemical oxygen demand (CODCr) and proton NMR, UV−vis, and spin trapping EPR spectroscopic evidence is presented to demonstrate the inverse photosensitized oxidative transformation of tetraethylatedExpand
Fenton Degradation of Malachite Green Catalyzed by Aromatic Additives
Fenton degradation of malachite green (MG) catalyzed by various kinds of aromatic additives was examined. It was found that the aromatic additives exhibited catalysis immediately or after anExpand
TiO2-mediated photocatalytic debromination of decabromodiphenyl ether: kinetics and intermediates.
TLDR
A potential application of photocatalysis in removal of PBDE contamination is provided by the rapid photoreductive debromination of decabromodiphenyl ether byTiO2 by TiO2. Expand
Efficient degradation of toxic organic pollutants with Ni2O3/TiO(2-x)Bx under visible irradiation.
TLDR
The study demonstrates that the modification of TiO2 both to extend its spectral response to the visible region and to improve its catalytic efficiency can be achieved by doping with boron, a nonmetal, and Ni2O3, a metal oxide. Expand
Efficient visible-light-induced photocatalytic disinfection on sulfur-doped nanocrystalline titania.
TLDR
Results from DMPO spin-trapping electron spin resonance measurements confirm the formation of hydroxyl radicals, which is the origin of the considerable bactericidal activity under visible light irradiation. Expand
TiO2-assisted photodegradation of dye pollutants : II. Adsorption and degradation kinetics of eosin in TiO2 dispersions under visible light irradiation
Abstract The TiO2-assisted photodegradation of anionic eosin has been examined in TiO2 aqueous dispersions under illumination by visible light. Eosin is easily decomposed photochemically by visibleExpand
Fenton degradation of organic compounds promoted by dyes under visible irradiation.
TLDR
It was found that the presence of dyes could accelerate greatly the Fenton reaction of organic compounds such as salicylic acid, sodium benzenesulfonate, benzyltrimethylammonium chloride, and trichloroacetic acid under visible irradiation and that a complete mineralization of those compounds could also be achieved.

Photocatalytic Degradation of Organic Pollutants Under Visible Light Irradiation
Several TiO2-based photocatalytic systems that have considerable visible light response have been developed, such as the photodegradation of organic pollutants on sensitized TiO2 by visible light,Expand
Photo-Fenton degradation of a dye under visible light irradiation
Abstract The photodegradation of Malachite Green (MG) under visible light irradiation (λ>470 nm) in the presence of Fe3+/H2O2 or Fe2+/H2O2 was studied in comparison with the dark reaction. It wasExpand
Semiconductor-mediated photodegradation of pollutants under visible-light irradiation.
TLDR
In this tutorial review, the unique mechanistic characteristics, the constitution of photodegradation systems and their performance are described and the involved radical reactions during the degradation are discussed. Expand
