Abstract

Two mesoporous and flexible acylamide-functionalized rht-type MOFs exhibit not only high excess unsaturation CO₂ uptake (157 wt%) at 20 bar and 273 K, but also good selectivity of CO₂/CH₄ (8.6) and CO₂/N₂ (34.3). The advantages of acylamide groups for CO₂ capture have been further confirmed by GCMC and first-principles calculations.
