摘要

等级孔分子筛材料因其兼具高效传质与择形催化的优势而成为当前分子筛研究领域热点，然而其传质优化机制的不明确是制约等级孔分子筛材料设计思路与发展方向的主要因素。简要介绍了等级孔分子筛材料研究现状，并重点对等级孔分子筛材料传质机制研究进展，包括当前研究所面临的挑战和研究策略等方面进行了综述，探讨了传质机制研究在等级孔分子筛材料研发过程的重要意义，并对未来发展方向进行了展望。

Abstract

The hierarchical zeolite has become a hotspot in the current molecular sieve research field due to its advantages of efficient mass transfer and shape selection catalysis.The unclear mass transfer optimization mechanism has become a bottleneck restricting the design and development of hierarchical zeolite.This paper briefly introduces recent research and development status of the hierarchical zeolite,reviewes with emphasis the research progress in mass transfer mechanism of Hierarchical zeolite,the current research challenges and the analysis of current research strategy etc,and discussed the significance of mass transfer mechanism in the research and development of graded porous molecular sieve materials and the prospect of future development.
