In the present work we
discuss the statistical mechanical framework for predicting the decoration of
metallic nanoparticles using electrochemical methods, in thermodynamic
equilibrium. It is found that depending on the interactions between the two
metals, controlled decoration may be achieved for core-shell nanoparticles in
undersaturation and oversaturation conditions. The concept of underpotential
deposition is discussed for the case of nanoparticles, with the finding that
this phenomenon may be size dependent.
