ABSTRACT

Uniform nanoalloys should be formally distinguished from core-shell metallic nanoparticles containing two or more metals and built of a nucleus/kernel (e.g., of metallic iron) and a covering shell (e.g., of Au), although sometimes these two terms are not strictly distinguished in different publications. Computer simulations, carried out13 to study the mechanism of formation of nanoparticles synthesized in microemulsions, allowed to express the main idea of obtaining nanoalloys or core-shell nanoparticles as follows: a core-shell structure is obtained when the reduction rates of both metals are very different, whereas a nanoalloy is obtained if both reaction rates are similar.
