英文摘要Mesostructured TiO2 was prepared hydrothermally using cetyltrimethylammonium bromide (CTAB) as the structure directing agent, and the mesoporous Ti-P-Al material with high thermal stability was subsequently synthesized by a two-step post-synthetic treatment. The sample was characterized by powder X-ray diffraction, transmission electron microscopy, and N-2 adsorption. It was found that the composition of the starting gel system greatly affected the mesostructure of TiO2 materials greatly. With the gel composition of Ti(SO4)(2): CTAB: H2O=1:0.54:430 and after being treated at 363 K for 10-20 min, an ordered TiO2 mesostructure was obtained, which presented better long-range order after being treated with 0.25 mol/L phosphoric acid solution. Further treatment with AlCl3 solution resulted in a mesoporous Ti-P-Al material with high thermal stability, which had a high BET specific surface area of 382 m(2)/g and a pore size of 3.13 nm after calcination at 873 K.
