Progress in Characterization Strategies Mass Transfer Mechanism of Hierarchical Zeolite

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.
