Nucleation phenomena in electrochemical systems: kinetic models

Abstract

The classical thermodynamics allow deriving theoretical expressions for the nucleation work and for the size of the critical nuclei in a supersaturated system. However, information on the rate of nucleus formation should be determined by means of kinetic considerations. This article sheds light on the nucleation kinetics in electrochemical systems at a constant thermodynamic supersaturation Δ μ~. Theoretical expressions are derived for the stationary and non-stationary nucleation rate.
