Paper Title:
Synthesis of Ag Core @ Au Shell Composite Nanoparticles by Spontaneous Deposit Au on the Surface of Ag Seeds
  Abstract

A new synthesis of Ag @ Au core-shell composite nanoparticles (NPs) was described by spontaneous deposit Au on the surface of Ag seeds which were prepared with the photochemical method in sodium citrate solution. The Ag core @ Au shell (or Ag core @ Au-Ag alloy shell) composite NPs with monodisperse and uniform shape were about 10 nm. The core/shell nanostructure was confirmed by UV-vis spectrum and TEM characterization as well as cyanide ion (CN-) dissolution experiment. The reaction mechanism of forming Ag @ Au composite NPs was briefly discussed.
