Review on Techniques to Improve Hydrothermal Stability of Mesoporous Zeolites

综述了近年来提出的各种提高中孔分子筛水热稳定性的方法 ,分析比较了各种方法的特点和存在的问题 。

In recent years, much attention has been paid to the synthesis of mesoporous zeolites for their potential applications in many petrochemical processes,particularly those dealing with conversion of large molecules. Various technologies developed to improve hydrothermal stability of mesoporous materials are reviewed in this article, and their pros and cons are analyzed. It is suggested that the synthesis of mesoporous aluminosilicate with ordered hexagonal structure, high acidity and excellent hydrothermal stability via self-assembly of alunminosilicate nanoclusters and novel template seems to be a new trend in this area.
