Front Cover: Dynamics of the Galvanic Replacement Reaction of Silver by Gold: Phenomenological Models for Open Circuit Potential‐Time Responsive Indicator (ChemElectroChem 22/2025)

The cover artwork depicts the electrochemical capture of concerted ion, electron, and atom motions during the galvanic replacement reaction (GRR) of silver by gold in silver nanoparticles. A mathematical model based on autocatalytic networks and cascade mechanisms explains the GRR output signal, which is the time- and concentration-dependent open-circuit potential. The model provides access to the kinetic parameters that describe the dynamics of this three-by-one galvanic exchange event.
