- Abstract:Bi-doped TiO2/SBA-15 (Bi-TiO2/SBA-15) was synthesized by wet impregnation method. It was found that SBA-15 retained the ordered hexagonal mesostructure after incorporation of TiO2 and Bi. TiO2 nanoparticles and Bi species dispersed well and anchored both in the channel and the wall of SBA-15. The photocatalytic activity was evaluated on photodegradation of Rhodamine B (RhB) under visible light irradiation (λ≥420nm). Experiment results indicated that Bi-TiO2/SBA-15 exhibited high photocatalytic activities than pure TiO2 and TiO2/SBA-15 owing to the synergetic effects of Bi species and TiO2. The degradation of RhB by these catalysts follows the pseudo-first-order kinetic model and Bi-TiO2/SBA-15 (2.0%) was found to be the best. The effect of Bi doping on the photocatalytic activity was investigated by density functional theory (DFT) method. The calculated results indicate that Bi doping could improve the photocatalytic activity by extending the spectral response from UV to visible region, making the Bi-TiO2/SBA-15 active under visible light irradiation.
