Abstract
Based on the theory of crystal engineering, the MIL-53(Al-Cr) with mixed cations was successfully synthesized by selecting the optimal synthesis conditions and molar ratio of Al and Cr salts. The breathing effect of MIL-53(Al-Cr) was studied by the X-ray thermodiffractogram. The porous structure of MIL-53(Al-Cr) was also obtained, which is different from that of MIL-53(Al) or MIL-53(Cr). The applications of MIL-53(Al-Cr) in the CO2 and VOCs adsorption were studied. The results indicated that the CO2 uptake of the MIL-53(Al-Cr) increased by 15% and 14% than MIL-53(Al) and MIL-53(Cr), respectively. Furthermore, the MIL-53(Al-Cr) easily adsorbed aniline in the mixed solution of aniline and phenol. The MIL-53(Al-Cr) is a proming material for CO2 and VOCs adsorption. The thermodynamic properties of Co(3,5-PDC)(H2O) and Al(NDC) were studied by using the temperature modulated differential scanning calorimetry (TMDSC). .
