Synthesis of ultrastable ordered mesoporous aluminosilicates molecular sieves with'hard template'

摘要

Ultrastable MSAMS-2 has been synthesized by the use of SBA-15 as"hard template"via twice re-crystallization both within the diluted solution of aluminosilicates sol-gel and glycerol.The ultrastable hydrothermal stability of MSAMS-2 might be ascribed to synergistic effect of the thicker wall,the higher condensation of silanol groups,the insertion of non-framework Al atoms and the formation of zeolites-like five-membered ring subunits within mesoporous framework.
