Nanocomposite membranes and methods of forming the same

Patent ·
OSTI ID:1892979
A nanocomposite including a mesoporous, macroporous, or a combination thereof oxide and a zeolitic imidazolate framework (ZIF) that is filling the pores of the oxide to form a ZIF phase embedded and at least substantially confined mostly within the oxide. Methods of making nanocomposites including the steps of depositing an oxide in the pores of a mesoporous oxide; and further treating the resulting material with vapor, liquid, or supercritical CO2 comprising an azole-based compound, a carboxylate based compound, or a combination thereof. Use of disclosed articles to separate propylene and propane in a mixture thereof.
