Using grand canonical Monte Carlo method, the capacities of CO2adsorption in IRMOF-12 and-14 are simulated at ambient conditions. We have theoretically found that CO2uptake can be greatly enhanced by either lithium doping or fullerene impregnating, and the influence of the Li doping is more significant than that of C60impregnation. Furthermore, the CO2storage capacities of IRMOFs after both Li doping and C60impregnating are improved to be about 30 times those of corresponding pristine structures. To further understand the mechanism, we analyzed the distribution pattern of CO2adsorption in materials and investigated the relationships between CO2uptakes and crystal density, surface area per volume and per mass, and pore volume per volume and per mass in detail.

This paper reports on the comparison of three zirconium-based metal organic frameworks (MOFs) for the capture of carbon dioxide and ethanol vapour at ambient conditions. In terms of efficiency, two parameters were evaluated by experimental and modeling means, namely the nature of the ligands and the size of the cavities. We demonstrated that amongst three Zr-based MOFs, MIP-202 has the highest affinity for CO2 (−50 kJ·mol−1 at low coverage against around −20 kJ·mol−1 for MOF-801 and Muc Zr MOF), which could be related to the presence of amino functions borne by its aspartic acid ligands as well as the presence of extra-framework anions. On the other side, regardless of the ligand size, these three materials were able to adsorb similar amounts of carbon dioxide at 1 atm (between 2 and 2.5 µmol·m−2 at 298 K). These experimental findings were consistent with modeling studies, despite chemisorption effects, which could not be taken into consideration by classical Monte Carlo simulations. Ethanol adsorption confirmed these results, higher enthalpies being found at low coverage for the three materials because of stronger van der Waals interactions. Two distinct sorption processes were proposed in the case of MIP-202 to explain the shape of the enthalpic profiles.
