摘要

Abstract

Two isomeric metal-organic frameworks (MOFs) with 2-dimensional (2D) and 3-dimensional (3D) topologies both comprised of Cu(II) and OTf (OTf=trifluoromethanesulfonate) ions were synthesized and characterized. The CO

and N

adsorption properties of the two isomeric MOFs were investigated from 263 K to 298 K at 0.1 MPa. The results showed that the 2D MOF exhibited a higher selectivity for CO

from CO

/CH

and CH

from CH

compared to the 3D MOF

even though it possessed a lower surface area and pore volume. The higher adsorption heats of gases on the 2D MOF inferred the strong adsorption potential energy in the layered MOFs. Dynamic separation experiments using CO

/CH

and CH

mixtures on the two MOFs proved that the 2D MOF had a longer elution time than the 3D MOF as well as better separation abilities.
