Preparation of Cu@Ag Core-Shell Nanoparticles Using a Two-step Polyol Process under Bubbling of N-2 Gas
Cu core-Ag shell nanoparticles, denoted as Cu@Ag, were prepared using a two-step polyol reduction process under bubbling N-2 gas. Formation of Cu@Ag particles with an average size of ca. 80nm was confirmed using energy-dispersed X-ray spectroscopic (EDS) measurements. The Cu particle oxidation was suppressed greatly by Ag shell covering.
