제목 Effect of Ionic Liquids on Dissociation of Copper Flakes into Copper Nanoparticles and Its Application to Facilitated Olefin Transport
초록 Effect of ionic liquids on dissociation of copper flakes into copper nanoparticles and on facilitated olefin transport was investigated. Three different ionic liquids were employed for facile synthesis of copper nanoparticles and for inducing the positive charge density of the copper nanoparticles for facilitated olefin transport. The separation performance of the ionic liquids/Cu metal composite membranes for olefin/paraffin mixtures was in the following order: EMIM+BF4/Cu 〈 BMIM+PF6 /Cu 〈 BMIM+BF4/Cu, surprisingly XPS spectra for the binding energy of the copper atoms in the ionic liquids/Cu metal composite was consistent with the trend for the separation performance. The size distribution of the synthesized copper nanoparticles was evaluated by TEM images and UV-visible spectra. Consequently, it was concluded that facilitated olefin transport was consistent with the trend of increasing binding energy of copper atoms.
