Post-synthetic modification of MIL 101(Cr)-NH2 frameworks was performed with a series of amines at different loadings and applied for the CO2 capture. At first, structural and morphological properties of MOFs were studied by Fourier transform spectroscopy (FTIR), scanning electron microscopy (SEM), thermal gravimetry analysis (TGA) and X-ray diffraction (XRD). Results confirm the successful synthesis of products. In the next step, CO2 adsorption of MOFs and potential applications in carbon capture were realized by the Low-pressure gas sorption measurements and CO2 cycling experiments analyses. Our findings highlighted the significant impact of various factors, such as the choice of amine, loading amount, temperature, and pressure, on the CO2 adsorption capacity of MOFs. Three distinct types of amines namely polyethyleneimine (PEI), diethylenetriamine (DETA), and ethylenediamine (ED) were employed for the functionalization of MOFs. The results unveiled a distinct hierarchy in the CO2 adsorption capacities of MOFs modified with these different amines. Specifically, the order of decreasing CO2 capacity for PSM materials was observed as follows: PEI > DETA > ED. This sequence underscores the varying impact of amine types on enhancing the adsorption potential of MOFs, offering valuable insights into optimizing these materials for efficient carbon capture applications.
