Synthesis and Characterization of a Novel Layered Zeolite MCM-56

Abstract

Abstract: MCM-56, a novel layered zeolite, has been synthesized under a stirring condition by hydrothermal method and characterized by XRD, TEM, TGand DTA. TEMshows that most of the crystals exist in the form of single layer. Based on the experimental facts and framework type which MCM-56 belongs to, MCM-56 should consist of very thin MWWtype layers which are just one unit cell along the c direction, and have a unique architecture with two dimensional10 MRpore system inside the layer and 12-MRcups(half of the MWWcages described in the MCm-22 or MCM-49) on the crystal exterior without cages between layers.
