Description
Summary:Materials Institute Lavoisier-101-D (MIL-101(Cr)-D) composites were first successfully synthesized by traditional solvent hydrothermal synthesis method. The effect of MIL-101(Cr) which was modified by DEA on CO 2 adsorption was studied and characterized by XRD, TGA, FT-IR, N 2 adsorption technique, and SEM. In order to compare the CO 2 adsorption of MIL-101(Cr) and MIL-101(Cr)-D composites, CO 2 fixed-bed adsorption experiment had been performed. The results demonstrated that MIL-101(Cr)-D-0.24 had the best CO 2 adsorption performance and was 33.3% higher than the unmodified one. The characterization results also confirmed that MIL-101(Cr)-D-0.24 had the largest specific surface area and specific pore volume. The SEM images showed that with the increase of DEA grafting, the unit cell could not continue to maintain the octahedral structure. The amount of CO 2 adsorption of MIL-101(Cr)-D was also reduced which was caused by the collapse of the pore structure. The grafting of DEA did not affect the thermal stability of MIL-101(Cr).
