✦ Synopsis

It is shown that the underpotential deposition of a Cd adatoms layer on Pb increases the speed of the electrochemical reduction of O2 in sulphuric acid medium. A Pb rotating disc electrode reveals a nondiffusional component A of the total currenl which is increased when Cd adatoms are present. It is suggested that the electrochemical reaction which is linked to this non-diffusional component is responsible for the observed effect.
