摘要
Au-Ag bimetallic nanoparticles were prepared by the sonochemical co-reduction of Au(III) and Ag(I) ions in aqueous solutions. TEM images indicate that the co-reduction of Au(III) and Ag(l) produces bimetallic nanoparticles with a Au core-Ag shell morphology. It is suggested that the fori-nation of core-shell morphology is due to the reduction order of the metal ions and the involvement of a polymer-Ag ion complex.
