Abstract

A new, highly porous acylamide-functionalized MOF with a (3,24)-connected rht-type network (HNUST-5) has been synthesized and structurally determined using powder X-ray diffraction. HNUST-5 exhibits a high BET surface area of 3643 m² g^-1, and a large CO₂ uptake capability (38.9 mmol g^-1 under 36 bar) with an excellent selectivity of CO₂/CH₄ (7.3) and CO₂/N₂ (32.5) at 273 K.
