High and selective CO2 capture by two mesoporous acylamide-functionalized rht-type metal-organic frameworks.
Two mesoporous and flexible acylamide-functionalized rht-type MOFs exhibit not only high excess unsaturation CO(2) uptake (157 wt%) at 20 bar and 273 K, but also good selectivity of CO(2)/CH(4) (8.6) and CO(2)/N(2) (34.3). The advantages of acylamide groups for CO(2) capture have been further confirmed by GCMC and first-principles calculations.
