Mesoporous zeolitic materials, which are defined as the crystalline zeolite materials containing a large amount of mesopores, have become an important topic in the field of porous catalyst materials. That is because they not only have high heat and hydrothermal stability, significant shape selectivity and high activity, but also improve the a sorption and diffusion of large molecules due to the presence of mesopores. Appropriately adjusting the structure of the pores and surface acidity becomes an effective way to improve the reaction efficiency and prolong the working lifetime of ZSM-5 zeolite. In this paper the research status of methods of synthesizing mesoporous Y and ZSM-5 zeolites is presented.
