摘要：

TiO2-montmorillonite(MMT) photocatalysts doped with vanadium and/or carbon were successfully synthesized by a sol-gel method It was novel that these photocatalysts had a high ratio of Ti/MMT, up to 120 mmol/g For comparison, TiO2 photocatalysts doped with vanadium and/or carbon were also prepared by the same method without MMT The as-prepared photocatalysts were characterized by XRD, BET, XPS, FTIR, UV-vis DRS and ICP. The vanadium and carbon species of the photocatalysts were detected by XPS. elemental analysis or FTIR The absorption edge of TiO2-MMT was blue-shifted compared to TiO2 by UV-vis DRS When a small amount of MMT was highly dispersed in the given TiO2 sol system, the silicate layers and the vacant cl-orbits of the transition metal ions of MMT had obvious effects on the microstructure and the photo-catalytic activities of the MMT-containing photocatalysts The degradation of aqueous sulphorhodamine B (SRB) on these photocatalysts was investigated under UV-vis irradiation (C) 2010 Elsevier B.V.
