摘要：
Supported zeolite Y membranes exhibiting exceptionally high CO2 selectivities when used in CO2/N2 gas 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.
