✦ Synopsis

The kinetics of the anodic oxidation of the compounds that can interact with the oxidized states on Ag electrode surface (formaldehyde, etc.) have been simulated with the assumption that the chemical interaction controls the anodic reaction specifically catalyzed by Ag nanostructures. Computer simulation has shown that the superposition of the two mechanisms of the anodic oxidation -the direct electrochemical oxidation and the oxidation that comprises chemical interaction of the oxidizable solute with the oxidized electrode surface -can cause the oscillations of the potential at a galvanostatic control similar to the oscillations that were observed in the experiment.
