1. A methane-selective mixed matrix membrane comprising:
a UiO-66 type organic-inorganic composite nanoporous material, a MIL-100 type organic-inorganic composite nanoporous material, or ZIF-8 type organic-inorganic composite nanoporous material; and
a polymer matrix,
wherein the methane-selective mixed matrix membrane has a methane permeability of 6 barrer or more and a methane/nitrogen selectivity of 5 or more from a mixed gas containing methane and nitrogen.
