Silicalite-1 has been prepared using a novel Si02-Xr02 porous glass tube as both a silica source and a substrate. The glass tube was found to possess sufficient physical strength to enable practical use as a separation and catalytic membrane after silicate-1 deposition within its channel. This is in contrast to porous Si02 glass which cannot be used to synthesize a silicalite-1 deposited membrane with enough physical strength to perform gas permeance measurements.
