In this report, we describe a simple and rapid chemical reduction method with inert gas
protection, for preparing stable copper nanoparticle with average particle size of 9.4 nm.
In our synthesis route, ascorbic acid is used as antioxidant to effectively prevent the
general oxidation process during copper nuclei formation. As-prepared copper
nanoparticles were transferred from water phase to different organic solvents (hexane,
octane, cyclohexane, and toluene) using oleylamine as a phase transfer agent. This
should allow dispersion of the particles in both polar and nonpolar solvents and avoid
particle aggregation during the solvent exchange process. Transmission electron
microscopy and UV–Vis spectroscopy contributed to the analysis of size and optical
properties of the copper nanoparticles in different media, respectively. The advantages
of such solvent exchange process can be found in the applications of metal particles as
catalysts for organic reactions in nonpolar solve...nts and in the study of the changes in
surface chemistry depending on the surrounding medium and on the adsorption of
different moieties.
