介孔ZSM-5沸石的制备与应用进展

Preparation and Application of Mesoporous ZSM-5 Zeolites

介孔ZSM-5沸石分子筛既具有丰富的孔结构、较高的酸性,又具有良好的传质性能和催化性能.介孔ZSM-5沸石的制备方法很多,归纳总结了两种主要制备方法:后处理法和模板法,并且阐述了介孔ZSM-5沸石作为催化剂的应用现状以及今后的研究发展方向.

Mesoporous ZSM-5 zeolites are characterized by substantial pore structures,high acidity,easy mass transfer performance and good catalytic properties. There are diversified methods on the preparation of mesoporous ZSM-5 zeolites. Two main methods are summarized in the paper,namely,post-treatment method and template method. The recent application status and the future development of mesoporous ZSM-5 zeolites as catalysts are also described.
