separations processes. For such purposes, the natural configuration of the zeolite material is in the form of a
thin film or membrane supported on, or deposited in, a porous substrate. ZSM-5 type zeolite membranes
have shown promise for molecular sieving applications that require high chemical and thermal stability.
ZSM-5 type zeolite membranes were prepared by template-free seeded growth method in order to minimize
defects and/or intercrystalline gaps that form during the calcination step required for template removal. In
many cases, microwave synthesis has proven to remarkably reduce the synthesis time. In addition,
microwave synthesis could also result in different membrane morphology, orientation, composition, and thus
the different permeation characteristics as compared with those synthesized by conventional heating.
