Much attention has been paid to micro/mesopore composite molecular sieves due to the combination of the advantages of both mesoporous molecular sieves and zeolites, possessing bimodel pore systems, and the adjustability of pore size and acidity. In this paper advances in the synthesis of micro/mesopore composite molecular sieves are reviewed and various methods of preparing these composite materials are introduced, such as in-situ crystallization, ex-situ crystallization, crystallization of mesopore walls and nanoclusters self-assembly. Furthermore. The prospect of micro/mesopore composite molecular sieves and the problems during their preparation are also presented.
