Abstract: The reduction of molecular oxygen was investigated on single crystal rutile electrodes. Cyclic voltammetry and a rotating ring-disk electrode were employed to elucidate the mechanism and energetics of the reaction. It was found that oxygen reduction proceeds through a surface species at potentials positive of the flatband potential in the electrolytes used. It was also demonstrated that the majority of the reaction proceeds via a 4-electron pathway while a small percentage of the oxygen is reduced by two electrons to hydrogen peroxide. © 1980.
