| Abstract: | Mesoporous titania powders with high specific surface area were prepared under hydrothermal conditions by employing β-cyclodextrin （CD） as template, and characterized by means of BET, XRD and N2 adsorption-sorption. The effects of the hydrothermal temperature, hydrothermal time, calcination temperature and template content on the specific surface area and photocatalytie performance of mesoporous titania were discussed. The mesoporous anatase titania powders with most probable pore size 4,3 nm and specific surface area 216.2m2g-1 were prepared while the hydrothermal temperature was 180℃, the hydrothermal time was 8h, the calcination temperature was 350℃ and β-CD/TiO2 =60wt%; and the powders had the best photocatalytic activity. |
