Résumé
Carbon dioxide and methane adsorption has been carried out up to 50 bar on the MIL-47(V) metal–organic framework (MOF) at 303 K. The so-obtained performance has been compared with other well-known MOFs, an activated carbon, and the zeolite NaY both in amount and volume adsorbed scales. In the latter scale, which would be of interest for real applications, the MIL-47(V) shows promising results similar to those of Cu3(BTC)2 or HKUST-1. Operando Infrared experiments have been employed to characterize the strength of the interactions in play. Finally, the CO2/CH4 separation properties have been further predicted using a combination of macroscopic and microscopic modeling approaches. This body of results suggests that this material should be considered for gas separation.
