Synthesis and Characterization of Mesoporous Molecular Sieve MCM-41 Prepared from Natural Clinoptilolite Zeolite

Mesoporous molecular sieves (NCZ-MCM-41) with ordered hexagonal structure have been synthesized from natural clinoptilolite zeolite (NCZ) with cetyltrimethylammonium bromide micelle under hydrothermal conditions in alkaline media. Zeolite P was also formed from NCZ under the conditions studied. The samples were characterized by XRD, N sub(2) adsorption and IR. It is indicated that the pore walls of the NCZ-MCM-41 may probably contain the secondary building units similar to NCZ and zeolite P.
