纳米分子筛的合成与应用进展

纳米分子筛具有短的孔道和较开放的晶穴,不仅在催化、离子交换、复合材料方面显示优异性能,而且在分子组装、光电磁功能纳米材料制备上是一种优良的载体材料或宿主材料.同时,对纳米分子筛的研究利于从深层次了解分子筛的核化和生长机理.介绍了纳米晶分子筛的合成、晶化特征及应用进展,进一步对新成分和结构分子筛、分子筛及纳米晶组装体系的新成果做了概述,指出了纳米分子筛研究的几个主要方向.

Progress on Synthesis and Applications of Nanocrystalline Zeolite

Nanocrystalline zeolite holds excellent properties in catalyst, ion-exchange, composite materials etc due to its very open channels and caves. It is the good host or substrate of molecular assembling, other nano-materials, such as photic, electronic, magnetic materials. Meanwhile, the nucleation and crystallization mechanism will be further confirmed by synthesizing and investigation of nanocrystalline zeolite. In this paper, the synthesis development of nanocrystalline zeolite is introduced and the new progresses in novel structure or chemical composition of zeolite are summarized. The main research directions are presented.
