“…A possible reaction mechanism for the oxidation of silver ions to AgO has been proposed by Dugdale et al (1961). that oxygen evolution occurs on silver metal when a Pb-Ag bielectrode (silver wire embedded in lead) is anodised in sulphuric acid, optical video microscopy of a Pb-Ag bielectrode anodised in sulphuric acid in the presence and absence of manganese revealed that the OER does not occur preferentially on silver metal but rather at the junction of the two metals.…”

The role of silver as an alloying additive to reduce the overpotential of the oxygen evolution reaction on lead anodes used in the electrowinning of zinc has not previously been established. This paper summarizes the results of a detailed study of the mechanism of the action of silver both as an additive to the alloy and in solution. The presence of Ag 2 O 2 in the oxide layer was confirmed on Pb electrodes anodised in sulphuric acid electrolytes containing silver ions. The enhanced electrochemical activity of PbAg alloy anodes over Pb is attributed to the presence of Ag 2 O 2 in the corrosion layer.

“…The formation of AgOH was observed in studies of the kinetics and mechanism of silver(I) oxide layer oxidation in the presence of OH Ϫ ions. [25][26][27][28] A similar development cannot possibly occur for the Au support. The Au 2 O 3 ⅐ H 2 O is more easily formed than Au(OH) 3 , which is not a true hydroxide.…”

“…The kinetics of the electrochemical formation of argentic oxide and of a-and P-lead dioxide have been examined recently.1-3 Measurements have been made at constant potential both of the oxidation of the sparingly soluble sulphate deposits 1. 5 and of the direct electrodeposition of the oxide from solutions of soluble salts on inert platinum substrates. 2.3 In all these cases it has been shown that nucleation of the new phase takes place at preferred sites and that the centres formed subsequently grow in two or three dimensions.…”
