OFe3 cation and amino-BDC anion preliminary building blocks forming structure of amino-MIL-101(Fe). [Display omitted] •The application of amino-MIL-101(Fe) has been assessed for CO2 capture.•A hybrid model was applied to correlate the experimental data at low pressures.•Kinetic adsorption data have been modeled by the theoretical micropore model. Amino-MIL-101(Fe) was synthesized and assessed for post-combustion CO2 capture. A hybrid model has been applied which resulted in better agreement with the experimental data. The achieved adsorption values for the pure CO2 and N2 gases at 1 bar and 298 K were equal to 0.41 and 0.33 mmol.g−1. The kinetic modeling of adsorption data indicated that the adsorption of CO2 and N2 at low pressure was not kinetically controlled. The adsorption selectivity of CO2 over N2 was estimated using IAST, which was achieved equal to 1.6.
