Cubic and Hexagonal Mesoporous Aluminosilicates Assembled from Secondary Building Units Characteristic of Zeolite Beta

Abstract:

To improve the structure order and catalytic activity of mesoporous materials, cubic (SBU-MCM-48) and hexagonal (SBU-MCM-41) mesoporous aluminosilicates containing secondary building units characteristic of zeolite Beta have been prepared, and characterized by means of XRD, N₂ adsorption, IR spectroscopy, catalytic cracking reaction compared with the corresponding MCM-41. We found that the introduction of secondary building units characteristic of zeolite Beta into the mesopore wall could be an effective route to improve the acidity of mesoporous materials. Moreover, cubic SBU-MCM-48 has been more active than hexagonal SBU-MCM-41 for cumene cracking reaction.
