摘要：
Ordered hexagonal mesoporous aluminosilicate (SBU-MCM-41) with secondary building units characteristic of zeolite Beta has been characterized and compared with the corresponding MCM-41 by means of XRD, SEM, N-2 adsorption, IR spectra of pyridine, catalytic cracking activity and hydrothermal treatment. The results indicate that the introduction of secondary building units characteristic of zeolite Beta into the mesopore wall is an effective route to improve the acidity and hydrothermal stability of mesoporous material.
