제목 Synthesis of Monodisperse Copper Nanoparticles by Utilizing 1-Butyl-3-methylimidazolium Nitrate for Facilitated Olefin Transport Membrane
초록 We successfully fabricated Cu nanoparticles from Cu flakes by utilizing the ionic liquid BMIM+NO3-. When BMIM+NO3– existing mostly in the free ion state was used for dissociation of Cu flakes, Cu nanoparticles were rapidly prepared in a relatively short amount of time compared to other ionic liquids. The favorable interaction between free NO3– of BMIM+NO3– and the Cu metal surface caused the flakes to dissociate in the ionic liquid, forming nanoparticles. The formation of Cu nanoparticles was confirmed by UV-vis spectral analysis and transmission electron microcopy (TEM) imaging, and the interaction of BMIM+NO3– with the Cu metal was confirmed by X-ray photoelectron spectroscopy (XPS).
