AgO nano-particles (NPs) were generated in ionic liquid 1-methyl-3-octylimidazolium tetrafluoroborate (Moim+BF 4 - ). The formation of Ag NPs was attributable to the favorable interaction between the surface of particles and counter-anions of ionic liquid. The generated AgO nano-particles in Moim+BF 4 - were confirmed by TEM and the average size was 40nm. Coordinative interactions of AgO NPs with Moim+BF 4 - were investigated by FT-Raman spectroscopy. The prepared Moim+BF 4 - /Ag NPs composites were utilized for CO2 separation membrane and consequently, CO2 separation performance for composite membranes was improved compared with neat Moim+BF 4 - . The ideal selectivity for CO2/N2 was 23.4 with a CO2 permeance of 18.7GPU was observed, while the neat Moim+BF 4 - membrane showed a selectivity of 15.9 and a CO2 permeance of 12.7GPU.
