英文摘要	Mesoporous aluminosilicates with improved hydrothermal stability were prepared via the controlled coassembly of zeolitic precursors and teos in alkaline media. xrd, n-2 sorption, and tem methods showed that the coassembled sample had hexagonal mesostructures, and the hydrothermal stability was largely improved compared to normal mcm-41. si-29 mas nmr spectra indicated that the product had higher cross-linking degree compared to normal mcm-41 through the extra introduction of protozeolitic nanoclusters. al-27 mas nmr spectra implied that most al species had been tetrahedrally incorporated into the framework. the catalytic cracking conversion rate of 1,3,5-triisopropylbenzene over this sample was as high as 97.66%. at the same time, the hydrolysis behavior of teos and synergic polymerization process of protozeolitic nanoclusters and silicate oligomers were outlined.
