Abstract
A UiO–66 membrane was synthesized on a porous Al2O3 support using an in–situ solvothermal method with a coordination modulation technique. The prepared UiO–66 membrane exhibited the CO2/N2 ideal separation factor of 5.5, which distinctly differ from the values of 0.80 in Knudsen diffusion. In pervaporation tests, the UiO–66 membrane showed the organic selectivity. The separation factor in 10 wt% EtOH/H2O and Acetone/H2O were 4.9 and 12.2, respectively. Additionally, we demonstrated the stable pervaporation perfomance of UiO–66 membrane in an ethanol/water mixture.
