Tetrahedral Crosslinking of Dia-type Nets into Zeolitic GIS-type Framework for Optimizing Stability and Gas Sorption

Abstract

By using the net-to-net assembly strategy and HSAB interaction principle, a zeolitic metal-organic framework (FJI-Y3) with GIS topology is synthesized and derived from the tetrahedral crosslinking of interpenetrating dia nets. FJI-Y3 has a stable framework structure (upon 280 oC) with an aperture of 6.7 Å and high Cu+ density of 1.14 Cu+/nm3. The activated sample FJI-Y3-ht exhibits very high D2 (250.1 cm3/g) and H2 (232.5 cm3/g) uptakes under 77 K and 1.06 Bar, as well as C2H2 uptakes of 147.8 cm3/cm3 under 298 K and 1.06 bar. Furthermore, n-C4H10/i-C4H10 adsorption selectivity in excess of 84 for FJI-Y3-ht indicates its outstanding sieving properties for meeting the industrial challenge of n-C4H10/i-C4H10 separation.
