摘要: Ionic liquid membranes have showed low permeance, due to high viscosity when utilized for gas separation, limiting their practical application despite advantages such as thermal stability and CO2 selectivity. In this study, Cu nanoparticles generated by redox reduction with Fe2+ ions porous KIT-6 were selectivity a permeable membrane. When positively polarized materials incorporated into ionic 1-butyl-3-methyl imidazolium tetrafluoroborate (BMIM BF4), the CO2/N2 CO2/CH4 of composite membrane was largely enhanced 16.4 23.4, respectively while neat BMIM BF4 5.0 4.8, respectively. Furthermore, permeance also from 17 50.7 GPU, compared These enhancements separation performance is attributed both facilitated transport NPs increase diffusivity materials.
