Nanoparticles with nominal structures of Au@ Ag (core@ shell) and Au@ Ag@ Au (core@
shell@ shell) were prepared using the sequential citrate reduction technique and …

Ag (Au) bimetallic core–shell nanoparticles were prepared by a new seed growth method.
Ascorbic acid was used to reduce the complex of HAuCl4 and …

Highly dispersed gold–silver core–shell nanoparticles were synthesized in a two-step
process. The stabilizer-free gold core particles with an average diameter of∼ 30nm were …

Gold, silver and gold–silver alloy nanoparticles were prepared under mild conditions using
microwave heating, polyacrylamide as a stabilizing agent and hydrazine hydrate as a …

Bimetallic gold-silver core-shell nanoparticles were prepared by chemical reduction in
aqueous solution, following a method that was friendly to the environment, allowing us to …

Pentagonal bipyramid-shaped gold-rich Au/Ag alloy nanoparticles are synthesized in
ethylene glycol (EG) in the presence of small amounts of AgNO3 and PVP without using Au …
