| 20080214882 | ACIDIC MESOSTRUCTURED ALUMINOSILICATES ASSEMBLED FROM SURFACTANT-MEDIATED ZEOLITE HYDROLYSIS PRODUCTS - The surfactant-mediated hydrolysis of ZSM-5 zeolite affords five-membered ring subunits that can be readily incorporated into the framework walls of a hexagonal mesostructured aluminosilicate, denoted MSU-Z.
