Abstract

Bi, As, Sb and Pb adatoms remain irreversibly adsorbed on platinum single crystal electrodes. These adatoms undergo reversible redox reactions in the adsorbed state. The measurement of the charge involved in this redox reaction, jointly with that involved in hydrogen adsorption/desorption on the adatom-free platinum sites are used to in situ characterize these systems and check their stability in different experimental conditions.
