Abstract
MIL-53(Cr), was hydrothermally synthesized under new reaction conditions (1:2:280). Solvent-replacement was used during the post treatment of MIL-53(Cr). The synthesized MIL-53(Cr) was characterized by XRD, TG, SEM and IGA, respectively, and its absorption performance was examined by the experiments of pure gas absorptions of N2, CO2, CH4, C2H4 and C2H6, respectively. The results show that using the new recipe can make the preparation of MIL-53(Cr) more stable, and the solvent-replacement method can remove the impurities from the porous channels of the MIL-53(Cr) almost completely and make the prepared MIL-53(Cr) with high purity. After post treatment, the specific surface area of the MIL-53(Cr) is 1355.9 m2·g-1, and via a series gas absorption experiments, the prepared MIL-53(Cr) shows a broad prospect in different applications.
