Synthesis and Characterization of Y/MCM-41 Composite Molecular Sieve
摘要
Abstract
The Y/MCM-41 composite molecular sieve was prepared by post-synthesis method and its performance was characterized by XRD,BET,N2 adsorption-desorption and so on.In addition,its hydrothermal stability was studied.The results showed that the optimized synthesis conditions are as follows:pH 1 1,CTAB and SiO 2 molar ratio of 0.1 5,crystallization time 48 h,and the composite molecular sieve had the properties of both mesoporous MCM-41 and microporous Y.The acidity and hydrothermal stability of composite molecular sieve were better than that of pure mesoporous MCM-41.关键词
