Tetrahedral crosslinking of dia-type nets into a zeolitic GIS-type framework for optimizing stability and gas sorption

Author affiliations

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 (at 280 °C) with an aperture of 6.7 Å and a high Cu+ density of 1.14 Cu+ nm−3. The activated sample FJI-Y3-ht exhibits very high D2 (250.1 cm3 g−1) and H2 (232.5 cm3 g−1) uptakes at 77 K and 1.06 Bar, as well as a C2H2 uptake of 147.8 cm3 cm−3 at 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.
