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.

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

The present invention relates to a nitrogen adsorbent having nitrogen selective adsorptivity by including an organic-inorganic hybrid nanoporous material having a coordinatively unsaturated metal site with density of 0.2 mmol/g to 10 mmol/g in a skeleton, surface or pore; and use thereof, such as a device separating nitrogen from a gas mixture containing nitrogen and methane, a pressure swing adsorption separation device and a temperature swing adsorption separation device for separating nitrogen provided, a method for separating nitrogen and methane from a gas mixture containing nitrogen and methane, a device for separating nitrogen, oxygen or argon, a method for separating nitrogen, oxygen or argon from a gas mixture containing nitrogen, oxygen or argon, and a method for preparing nitrogen or high purity inert gas all separated from a gas mixture containing nitrogen and inert gas.

Inorganic-organic hybrid nanoporous material with nitrogen selective adsorptivity and method for separating nitrogen-containing gas mixture using the same
