Synthesis of high-crystallinity MIL-125 with outstanding xylene isomer separation performance
نویسندگان
چکیده
MIL-125 is a metal-organic framework with great potential for the adsorption and separation of xylene isomers. However, usually synthesized under anhydrous anaerobic conditions. In this study, homogeneously shaped highly crystalline was by introducing water-resistant titanium-containing oligomers into synthesis process. With assistance novel oligomers, can be in presence water, which meets batch-production requirements. The performance obtained also significantly enhanced. para-xylene/meta-xylene selectivity reach 13.5 mesitylene, higher than values most previously reported para-selective adsorbents. verified using both batch breakthrough experiments liquid phase. addition, influence solvent effect evaluated through microcalorimetric experiments, liquid-phase theoretical calculations.

MIL-53-Cu has been synthesized hydrothermally and has been used for the first time for gas separation. MIL-53-Cu shows adsorption capacities of 8.1, 0.7 and 0.5 m.mol/g, respectively, for CH4, CO2 and H2 at 30 bar and 298 K. The high CH4 adsorption capacity of MIL-53-Cu maybe attributed to the high pore volume and large number of open metal sites....
