%X The zeolite silicalite-1 composite membranes on porous carbon tubes were successfully prepared by using a simple seeded synthesis from clear solutions. SEM, XRD and single gas permeation characterization indicate that the membrane is dense, free-defected and shows good permeation properties. H2/C3H8 ideal selectivity for the membrane is over 15 at room temperature. Zeolite seeds are easily introduced into the porous carbon surface by a slip-casting technique from seed ethanol solution instead of water solution. The continuous seed layer on the carbon support favors the formation of the perfect membrane. The organic template from the composite membrane can be removed by calcination at 793K under nitrogen flow. This opens up the route for the preparation of carbon-zeolite films on porous carbon materials and also develops a novel method for tailoring and improving carbon pore structure of porous carbon materials.
