This article systematically introduces the synthesis methods for ZSM-5-based composite molecular sieve,and elaborates on the regulation methods and laws of the composite structure,such as the typical core-shell structure and micro-mesoporous structure,on its pore structure,acidity,and hydrothermal stability.Based on this,the applications of ZSM-5 composite molecular sieve are described in the production of low carbon olefins via catalytic cracking of methanol,light hydrocarbons,biomass,and their mixed feedstock.Finally,the perspectives of composite molecular sieve catalytic materials are proposed.
