Abstract：In this paper, recent researches progress on construction of hierarchical porosity and morphology control of zeolite materials were briefly reviewed: Firstly, various kinds of preparation methods of hierarchical porous zeolites were introduced, such as muti-templates method, controlled corrosion on zeolite framework, and dry gel conversion method on bi-continuous macroporous silica-aluminal monolith, etc. Then, characteristics of hierarchical porous zeolite materials, such as pore connection and acidity, were studied. It was shown that the mesopores and micropores inside hierarchical porous zeolite were well connected, more acid sites were accessible as well as more acid sites on external surface than conventional zeolite, and hierarchical porosity also accounted for the decrease of B acid and increase of L acid. Finally, the relationship between the hierarchical porosity and their catalytic performances were discussed. It was revealed that hierarchical porosity was of benefit to the catalytic conversion of relative larger molecular reactants, selectivity of larger molecular products, and anti-coke properties, which would postpone the deactivation of such zeolitic catalytic materials.
