Abstract

In this paper, TiO2 photocatalyst with enhanced photocatalytic activity was prepared by Sol-Gel method with the assistance of urea. The specific surface area, structure, and the hydroxyl content were characterized by Brunauer-Emmett- Teller (BET) measurements, X-ray diffraction (XRD), and FT-IR, respectively. The results show that adding urea into the synthetic system alters the specific surface parameters and hydroxyl content. The photocatalytic activity for decolorization of rhodamine B (RhB) aqueous solution was investigated. The results show that the photocatalytic decolorization of rhodamine B aqueous solution over TiO2 prepared with the assistance of urea is more than four times of that over the reference TiO2 and the underlying mechanisms are discussed.
