Abstract: Aseries of macroporous silicates with zeolitic microporous frameworks have been successfully prepared by self-assembly of discrete colloidal crystals of silicalite-1, titanium silicalite 1(TS-1) and ZSM-5 , using polystyrene(PS) spheres as templates. The properties of these novel materials were characterized by means of XRD, IR, SEM, 29Si MAS NMRand N2 adsorption/desorption measurements. These materials show ordered spheroidal voids, which are interconnected in three dimensions through windows. The ordering of the macropores are mainly affected by the particle size of the colloidal zeolites.

Key words: Colloidal zeolites, Self-assembly, Micro/macroporous bimodal pore systems, Polystyrene(PS) spheres
