A Microporous Metal–Organic Framework for Efficient C₂H₂/CO₂ and C₂H₆/CH₄ Separation

Abstract

Owing to the critical industrial value, the applications of MOFs in the field of light hydrocarbon gases storage and separation have attracted increasing attention. In this work, a microporous material, which is composed of typical dicopper paddlewheels and diisophthalate ligands, has been successfully synthesized. It exhibits good gas separation ability for C2H2/CO2 mixtures and C2H6/CH4 mixtures, respectively. Confirmed by the breakthrough experiments, the separation time of C2H2/CO2 mixtures (50/50) and C2H6/CH4 mixtures (15/85) can reach up to 36 and 95 min/g, respectively (gas flow rate = 2 cm3/min).
