Formation of Silicalite‐1 in Channels of Novel SiO2–ZrO2 Porous Glass Tubes Used as Both a Silica Source and a Substrate

Abstract

Silicalite‐1 has been prepared using a novel SiO2–ZrO2 porous glass tube as both a silica source and a substrate. The SiO2–ZrO2 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 SiO2 glass which cannot be used to synthesize a silicalite‐1 deposited membrane with enough physical strength to perform gas permeance measurements.
