Cationic Polymer Used to Capture Zeolite Precursor Particles for the Facile Synthesis of Oriented Zeolite LTA Molecular Sieve Membrane

A novel synthesis strategy is developed for the facile synthesis of a uniform, dense, and oriented zeolite LTA molecular sieve membranes by using the cationic polymer to capture the zeolite precursor particles during hydrothermal synthesis. The obtained zeolite LTA membranes display molecular sieving performance in shape-selective mixture gas separation.
