The mechanism of oxygen reduction at rhodium electrodes was studied using the rotating disk electrode with a concentric ring. At pre-reduced, oxide free electrodes no H2O2 is formed either as an intermediate or in a reaction parallel to that of H2O formation. In the presence of impurities H2O2 is produced in a parallel reaction to the main path for H2O production. At preoxidized Rh electrode, some H2O2 is produced, apparently in a path parallel to the main reduction path to H2O. The mechanism of O2 reaction on Ir electrodes was also determined. The path is the electrochemical oxide path. Author
