摘要
介孔ZSM-5沸石具备良好的水热稳定性、形状选择性和活性,对大分子扩散有较好的扩散性能,逐渐成为催化材料研究领域的热点。本文综述了近年来介孔ZSM-5沸石的研究进展,重点介绍了介孔ZSM-5沸石的不同合成方法,包括后处理法、模板法和无介孔模板剂法,同时通过对比不同制备方法,指出各种方法的优缺点,最后对介孔ZSM-5沸石的合成与催化发展进行了展望,认为研发简单、经济和环保的新合成路线是介孔ZSM-5沸石今后的研究方向。
Mesoporous ZSM-5 zeolite material possesses high hydrothermal stability, shape-selective catalysis and favorable acidity, excellent mass transport of the mesoporous structures, it has potential applications in catalytic field. The research progress of mesoporous ZSM-5 zeolite in recent years are reviewed in this paper, with the main focus on the synthesis strategies including post-treatment method, template method and template-free method. In addition, by comparing different preparation methods, the strengths and weaknesses of various methods is pointed out. Finally, the development of the synthesis and catalytic application of mesoporous ZSM-5 zeolites is prospected.It was proposed that the main development trend is to make more further studies on the development of facile, economic and green routes towards the synthesis of mesoporous ZSM-5 zeolite.
