Abstract

The photocatalyzed degradation of Acid Blue 40, a textile dye, in aqueous suspension of TiO2 has been studied by monitoring the change in dye concentration and formation of carbon dioxide as a function of irradiation time. Mechanistic studies suggest that in addition to the reaction of the hydroxyl and superoxide radicals with the dye, electron transfer from the photoexcited TiO2 to the dye forms a significant pathway in the photodegradation process.
