摘要: Abstract In very recent years there has been some conflicting information in the literature regarding initial stages of formation a multilayer Ag2O by anodic oxidation Ag aqueous alkaline solutions. We have re-examined and pre-Ag2O means cyclic voltammetry, rotating disk ring electrode techniques to help resolve controversy. Our results support conclusion that is one electron dissolution step controlled diffusion soluble species, Ag(OH)−2, away from surface. Additionally our electrochemical findings throw light on surface phases during process growth.
