Abstract

According to one or more embodiments, cationic polymers may be produced which include one or more monomers containing cations. Such cationic polymers may be utilized as structure directing agents to form mesoporous zeolites. The mesoporous zeolites may include micropores as well as mesopores, and may have a surface area of greater than 350 m 2 /g and a pore volume of greater than 0.3 cm 3 /g. Also described are core/shell zeolites, where at least the shell portion includes a mesoporous zeolite material.
