A new honeycomb MOF for C2H4purification and C3H6enrichment by separating methanol to olefin products

A new C 3 H 6 -selective MOF based on infinite helix SBUs was constructed, realizing the effective separation of C 2 H 4 –C 3 H 6 to not only yield ≥99.9% purity of C 2 H 4 by a one-step method but also greatly increase the purity of C 3 H 6 in the adsorbed mixtures.
