Abstract

The electroreduction reaction of molecular oxygen on the silver-nanocomposite based on sulphocation
exchanger CU-23, sulpho-cation exchange membrane MC-40 and a bulk silver electrode with deposited
particles of silver was studied. It was found that at the amount of the deposited metal were
εAg0 = 1.87 mmol/cm3 for Ag0·CU-23 and εAg0 = 3.03 mmol/cm3 for Ag0·MC-40 the formation of the
conjugated metal system was observed. The specificity of the oxygen electroreduction reaction on dispersed
silver in contrast to its bulk state is the participation of protons H+ in the stage when the first electron connects
to the oxygen molecule
