Abstract:

Hierarchical zeolites with intracrystalline mesopores exhibit the characteristic features of microporous zeolites and mesoporous materials, offering improved mass transport property and catalytic performance for zeolite materials. Development of mesoporous zeolites for catalysis, adsorption and separation has been significantly advanced in the past decades. In particular, several new synthesis strategies have been invented, which provided a wide range of flexibility and turnability to control the mesoporosity, composition and morpho-logy of mesoporous zeolites. In the short review, we focus on the recent advances in different synthesis strategies. Particular emphasis is given to the recently developed post-synthetic methods for the synthesis of low Si/Al ratio mesoporous zeolites, synthesis of mesoporous zeolites by supramolecular self-assembly and in situ synthesis of mesoporous zeolites using small organic molecules. The formation mechanisms associated with the synthesis approaches are discussed in order to provide insights into future development of mesoporous zeolites. At the end of this review, we discuss some critical challenges regarding the synthesis of mesoporous zeolites using the different synthesis strategies.
