Methods for synthesis of hierarchically ordered crystalline microporous materials with long-range mesoporous order

A method for synthesis of hierarchically ordered zeolite having FAU framework having long-range mesoporous ordering by dissolution/incision of a parent zeolite having FAU framework having micropores of 7.4 angstroms into oligomeric components, and reorganization into hierarchically ordered mesostructures, the method comprising:

• mixing the parent zeolite having FAU framework,
• a base selected from the group consisting of ammonia, ammonium hydroxide and urea, and
• a supramolecular template that is a quaternary ammonium moiety comprising a terminal C6-C24 alkyl group and a head group comprising a moiety selected from the group consisting of organosilanes, hydroxysilyls, and alkoxysilyls;
• to form an aqueous suspension,
• hydrothermally treating the aqueous suspension at a temperature of 110-250° C. to dissolve the parent zeolite having FAU framework by forming oligomeric units of the parent zeolite having FAU framework, and then form a solid hierarchically ordered mesostructure comprising mesopore periodicity repeating over a length of greater than 50 nm.
