Beschreibung
Zusammenfassung:	A method of preparing a supported gas separation membrane, comprising: preparing crystalline seeds from a synthesis mixture comprising an aluminum source, a phosphorous source, a silicon source, at least one organic templating agent and water; applying the seeds to a porous support to produce a seeded porous support; contacting the seeded porous support with a synthesis gel under hydrothermal synthesis conditions to produce a coated porous support; and calcining the coated porous support is described. A supported gas separation membrane made by this method is also described.
