We report on thermodynamic modeling and computer simulations on the electrochemical
generation of metallic and bimetallic nanoparticles (NPs) by means of quenched molecular
dynamics (QMD). The present results suggest that the spontaneous formation of core-shell NPs
depends on several factors, i.e. size and shape of the core, chemical composition of the system,
and under-/oversaturation conditions. Homo- and heteroatomic prototypical systems were
considered. The former systems were Au and Pt. The latter were Ag(core)/Au(shell),
Pt(core)/Au(shell), Au(core)/Ag(shell) and Au(core)/Pt(shell).
