An aliphatic MOF with a molecular sieving effect for efficient C2H2/C2H4 separation

Abstract

A metal–organic framework, SDMOF-1, with rigid pores of about 3.4 Å, which is appropriate for accommodating C₂H₂ molecules, exhibits high C₂H₂ adsorption capacity and great separation capability of the C₂H₂/C₂H₄ mixture. This work provides a new method to design aliphatic MOFs with a molecular sieving effect to realize efficient gas separation.
