Abstract
Silicalite membranes have been prepared using a novel seeding method. By sonicating silicalite seed crystals in the presence of a stainless steel mesh followed by a controlled hydrothermal synthesis step it has been shown by AFM, SEM, and simple diffusion measurements that coherent membranes are produced. The sonication step anchors the nanometer-sized zeolite seeds to the porous stainless steel support and the subsequent hydrothermal growth produces a zeolite membrane grown on this seed layer. © 1999 American Chemical Society.
