摘要：

Different alkylamine molecules were post-synthetically tethered to the unsaturated Cr-III centers in the metal-organic framework MIL-101. The resultant metal-organic frameworks show almost no N-2 adsorption with significantly enhanced CO2 capture under ambient conditions as a result of the interaction between amine groups and CO2 molecules. Given the extraordinary stability, high CO2 uptake, ultrahigh CO2/N-2 selectivity, and mild regeneration energy, MIL-101-diethylenetriamine holds exceptional promise for post-combustion CO2 capture and CO2/N-2 separation.
