Oriented assembly of zeolite crystals on a porous support followed by secondary growth leads to continuous, thin, uniformly oriented zeolite films (see picture for a cross-sectional SEM image) of MFI with the 5.1 x 5.5-Å zigzag channels perpendicular to the support. These a-oriented films along with their previously reported b-oriented counterparts are the first set of thin molecular-sieve membranes with uniform but drastically different orientations. (Figure Presented).
