Methane-selective mixed matrix membranes including nanoporous metal-organic framework materials to which a methane-selective functional group is introduced, the use thereof, and a method of preparing the same

Abstract

Provided are a methane-selective composite membrane comprising: a UiO-66 type organic-inorganic composite nanoporous material, a MIL-100 type organic-inorganic composite nanoporous material, or a ZIF-8 type organic-inorganic composite nanoporous material to which a methane-selective functional group is introduced for selectively separating methane from a gas mixture containing methane/nitrogen, a use thereof, and a method of preparing the same.

Dependencies are inferred from the claim text.
