Preparation of Cu@Ag Core–Shell Nanoparticles Using a Two-step Polyol Process under Bubbling of N2 Gas

Cu core–Ag shell nanoparticles, denoted as Cu@Ag, were prepared using a two-step polyol reduction process under bubbling N2 gas. Formation of Cu@Ag particles with an average size of ca. 80 nm was confirmed using energy-dispersed X-ray spectroscopic (EDS) measurements. The Cu particle oxidation was s...

Zusammenfassung:Cu core–Ag shell nanoparticles, denoted as Cu@Ag, were prepared using a two-step polyol reduction process under bubbling N2 gas. Formation of Cu@Ag particles with an average size of ca. 80 nm was confirmed using energy-dispersed X-ray spectroscopic (EDS) measurements. The Cu particle oxidation was suppressed greatly by Ag shell covering.
