Claim:
1. A method of forming a material comprising at least one mesoporous zeolite, said method comprising: (a) subjecting an initial zeolite to a framework modification process thereby producing a framework-modified zeolite, wherein said framework modification process comprises contacting at least a portion of said initial zeolite with an acid; and (b) forming a plurality of mesopores in at least a portion of said framework-modified zeolite thereby forming said mesoporous zeolite, wherein said forming comprises contacting at least a portion of said framework-modified zeolite with a base; wherein said forming of step (b) is performed in the substantial absence of a surfactant, wherein said framework-modified zeolite has not been subjected to drying prior to said forming of step (b), wherein said initial zeolite is selected from the group consisting of zeolite A, faujasites, mordenite, CHA, ZSM-5, ZSM-12, ZSM-22, beta zeolite, synthetic ferrierite (ZSM-35), synthetic mordenite, and mixtures of two or more thereof, wherein said initial zeolite has a framework silicon-to-aluminum ratio (“Si/Al”) of less than 30, and wherein said framework-modified zeolite has a crystalline content that is less than the crystalline content of said initial zeolite as measured by X-ray diffraction (“XRD”).
