Mechanism Investigation of Visible Light-Induced Degradation in a Heterogeneous TiO2/Eosin Y/Rhodamine B System
TL;DR: The results showed that the photodegradation of RhB is enhanced significantly when EO is introduced into the P-25/RhB system, and it can be deduced that dissolved O(2) plays a crucial role in dye photodegrading and the O(*-) anion is possibly the major active oxygen species.
