Abstract

Oriented ZSM-5 zeolite membranes on the biomorphic porous SiSiC ceramics were successfully synthesized by in situ hydrothermal synthesis. The ZSM-5/ SiSiC composite materials were characterized by XRD, SEM-EDX and BET. The effects of synthesis time and surface pre-treatment of the beech-derived SiSiC monolith were systematically studied. It shows that a homogeneous coverage within the pores channel of SiSiC monolith by b-oriented ZSM-5 crystals with 1μm average size is formed after hydrothermal treatment at 150℃ for 15h. The structure composites exhibit a hierarchical pore structure with a BET specific surface area of 42.8m2/g and microporous volume of 0.015cm3/g. The weight percent of ZSM-5 in the final zeolite/SiSiC composites is about 8.6% after coating.
