Novel Cage-Based Metal−Organic Frameworks for Efficient Separation of Light Hydrocarbons

A novel 3D MOF, SDU-CP-8, features an ellipsoid-shaped cage and a 3-nodal, (4,6,8)-connected network. It demonstrates excellent adsorption and separation capabilities for C 3 H 8 /C 2 H 6 /CH 4 and C 2 H 2 /CO 2 gas mixtures.
