| Abstract: | CTAB was used as template to systhesis mesoporous Titanium Dioxide by the method of hydrothermat. Rose bengal was used as dye-sensitizer to prepare photocatalytic catalyst which had photocatalytic activity under visible light. The samples were characterized by UV-Vis, XRD, FT-IR and BET method respectively. The photocatalytic activities of prepared samples were investigated by photocatalytic decomposition of water into hydrogen. The results indicated that the as-preoared TiO2 had higher surface area and higher photocatalytic activity, activity order：mesoporous TiO2〉P25〉sol-gel TiO2（calcined at 500 ℃）. |
