Abstract
AbstractThe RRDE multicycle chronoammetry makes it possible to obtain separately the partial currents of silver ionization, anodic oxide formation, and chemical oxide dissolution. In the range of low anodic potentials (0.48–0.51 V), the process of active silver dissolution from the open parts of the surface and through the pores of oxide film prevails; the phase formation current drops fast. At higher potentials (0.52–0.53 V), the phase formation current prevails and noticeably exceeds the rate of the chemical oxide dissolution. The thickness of Ag2O film rapidly increases; and the net phase formation current is close to 100% during the whole period of polarization. Ag(I) oxide is an n‐type semiconductor with an excess of silver atoms. Their concentration in the oxide film formed on monocrystalline Ag(111), Ag(110), and Ag(100) is less than in the film formed on polycrystalline Ag. Copyright © 2008 John Wiley & Sons, Ltd.
