Gas-phase photocatalytic oxidation of benzene over titanium dioxide loaded on Bi₁₂TiO₂₀

College of Chemistry, Sichuan University, Chengdu 610064, China

Received Date: 30 August 2006

TiO₂ was prepared by sol-gel method using tetrabutyl titanate as precursor. TiO₂ was loaded on Bi₁₂TiO₂₀. The photocatalyst with different TiO₂ loading was calcined at 723 K. The photocatalytic activity of decomposition gaseous benzene was investigated in a batch reactor. The prepared photocatalyst was characterized by UV-vis diffuse reflectance. The result showed that TiO₂/Bi₁₂TiO₂₀ absorbed much more ultraviolet light than TiO₂ in the ultraviolet light region and showed red shift. The results indicated that the prepared photocatalyst can greatly promote the photocatalytic activity. The 2.0% TiO₂/Bi₁₂TiO₂0 system exhibited the highest photocatalytic activity.
