A perfect match : Silver deposition is one of the fastest electrochemical reactions, even though the Ag + ion loses more than 5 eV solvation energy in the process. This phenomenon, an example of the enigma of metal deposition, was investigated by a combination of MD simulations, DFT, and specially developed theory. At the surface, the Ag + ion experiences a strong interaction with the sp band of silver, which catalyzes the reaction.
