Surface Chemistry of TiO2 and its Adsorption and Photodegradation of Orange II in Water Solution

Abstract:

In this study, the surface chemistry of TiO2 and related photochemical reaction process was reported by taking Orange II, an azo dye, as an example. The results revealed that major oxidative species is HO instead of hole, though hole is also an oxidative species in some other conditions. Besides that, this article also analysed the reaction process, which involves adsorption-reaction-desorption, three typical steps. For reactions falling in the category of these three steps, Langmuir-Hinshelwood model fit best, because it deals with the adsorption and chemical reaction, a dual process..
