Sažetak
The kinetics of anodic dissolution of silver and Ag-Au alloys (xAu = 0.1–30 %) in aqueous alkaline
solution under the conditions of AgI oxide formation has been examined. Using the techniques
of cyclic voltammetry and chronoamperometry it has been established that Ag2O anodic
formation and cathodic reduction on silver and on alloys of all compositions under review are
controlled by Ag+ cation migration in the oxide layer. The oxide film consists of a thin inner
layer (apparently AgOH) and of a thicker outer layer Ag2O. These layers slightly differ in specific
electro-conductivity. Using the photopotential measurements it has been shown that
Ag2O oxide is an n-type semiconductor with an excess of silver atoms. The AgI oxide layer
formed on monocrystalline Ag(111) is more stoichiometric than the layer formed on polycrystalline
Ag.
