Abstract

TiO₂/BaBiO₃ composites were prepared through a pore impregnating method and characterized by Brunauer-Emmett-Teller method, X-ray diffraction, UV-Vis diffuse reflectance, and X-ray photoelectron spectroscopic techniques. The composites exhibit higher photocatalytic activity than pure TiO₂ toward degradation of gaseous benzene under ultraviolet light irradiation. The effects of TiO₂ loading on the photocatalytic activity were investigated and the optimization of the TiO₂/BaBiO₃ composite was obtained. The enhanced mechanism was also suggested.
