Disclosed herein are membranes comprising a substrate, a support layer, and a selective layer. In some embodiments the membrane may further comprise a permeable layer. Methods of forming membranes are also disclosed comprising forming a support layer on a substrate, removing adsorbed species from the support layer, preparing a solution containing inorganic materials of a selective layer, contacting the support layer with the solution, drying the membrane, and exposing the membrane to rapid thermal processing. Also disclosed are methods of fluid purification comprising providing a membrane having a feed side and a permeable side, passing a fluid mixture across the feed side of the membrane, providing a driving force for transmembrane permeation, removing from the permeate side a permeate stream enriched in a purified fluid, and withdrawing from the feed side a fluid that is depleted in a purified fluid.

Systems, compositions, and methods for fluid purification

Supported zeolite Y membranes exhibiting exceptionally high CO2 selectivities when used in CO/Ngas separations are produced by a seeding/secondary (hypothermal) growth approach in which a structure directing agent such as tetramethylammonium hydroxide is included in the aqueous crystal-growing composition used for membrane formation.
