Preparation of ZSM-5 nanozeolite membrane on porous α-alumina support by seeding technique

Nano crystalline Silicalite-1 (crystal size in the range of 50-150 nm) has been synthesized in only 72 h. by crystallization of clear homogeneous synthesis mixtures using reflux technique. Porous α-alumina supports were seeded with colloidal TPA-silicslite-1 nano crystals and calcined. The supports were treated in a solution to grow the seed nano crystals into zsm-5 films. The membranes were characterized by using scanning electron microscopy (SEM) and X-ray diffraction (XRD).
