Photoassisted Degradation of Dye Pollutants. V. Self-Photosensitized Oxidative Transformation of Rhodamine B under Visible Light Irradiation in Aqueous TiO2 Dispersions
TL;DR: In this article, the inverse photosensitized oxidative transformation of tetraethylated rhodamine (RhB) under visible illumination of aqueous titania dispersions is demonstrated.
Journal ArticleDOI
Photooxidation Pathway of Sulforhodamine-B. Dependence on the Adsorption Mode on TiO2 Exposed to Visible Light Radiation
TL;DR: In this paper, the temporal course of photooxidation of sulforhodamine-B in aqueous media illuminated by visible wavelengths in the presence of TiO2 has been examined to determine the nature of the intermediate species produced and to explore the operative reaction pathway(s).
Journal ArticleDOI
Photoassisted Degradation of Dye Pollutants. 8. Irreversible Degradation of Alizarin Red under Visible Light Radiation in Air-Equilibrated Aqueous TiO2 Dispersions
TL;DR: In this article, the photo-assisted degradation of alizarin red mediated by TiO2 particles under visible light radiation was proposed, and the photodegradation kinetics were discussed in terms of the Langmuir−Hinshelwood model, a case of saturation type kinetics.
Journal ArticleDOI
Evidence for H2O2 Generation during the TiO2-Assisted Photodegradation of Dyes in Aqueous Dispersions under Visible Light Illumination
TL;DR: In this paper, a series of dyes (Rhodamine B, Orange II, Sulfo-rhodamines B, Fluorescein, Alizarin red, Squarylium cyanine, and Eosin) in the presence of TiO2 particles under air-equilibrated controlled conditions and visible light illumination led to the formation of hydrogen peroxide.
Journal ArticleDOI
Photooxidation mechanism of dye alizarin red in TiO2 dispersions under visible illumination: an experimental and theoretical examination
TL;DR: In this article, the ESR spin-trapping technique was used to detect active oxygen radicals formed during in situ visible irradiation of alizarin red/TiO2 dispersions.
