Abstract

According to one or more embodiments disclosed herein, a mesoporous zeolite may be made by a method comprising contacting an initial zeolite material with ammonium hexafluorosilicate to modify the framework of the initial zeolite material, and forming mesopores in the framework-modified zeolite material. The contacting may form a framework-modified zeolite material. The mesoporous zeolites may be incorporated into catalysts.
