| 英文摘要 | a microporous zeolite utm-1 was prepared and transferred to mcm-41 type materials by refluxing with surfactant at the presence of naoh and by a subsequent ph adjusting process. the ph value affected the long-range order of these mesostructures greatly, and mcm-41 type products were obtained at ph = 7 and ph = 5 (designated as ms-7 and ms-5, respectively). the as-synthesized ms-7 showed smaller particle sizes (about 500 nm) and cylindrical pores. ms-7 showed a high bet specific surface area of 1003 m(2)/g and a high pore volume of 1.20 cm(3)/g after calcination at 823 k as well as two pore size distributions centred at 2.4 and 3.7 nm, respectively. the calcined ms-7 exhibited remarkable hydrothermal stability. after being treated in boiling water for 312 h, the material remained a high bet specific surface area of 922 m(2)/g and a high pore volume of 1.08 cm(3)/g without degrading its well-ordered mesostructure. compared with ms-7, the 823 k calcined mcm-41 showed poor hydrothermal stability and preserved only a bet specific surface area of 150 m(2)/g and a pore volume of 0.35 cm(3)/g upon being treated in boiling water for 24 h. the remarkable hydrothermal stability of ms-7 was ascribed by solid-state nmr results to the presence of higher percentage of 4-fold coordinated al species and the highly polymerized pore walls.
