Abstract
Oxygen evolution reactions1 are critical to the development of efficient energy conversion and energy storage devices. For example, power losses at the oxygen electrodes of commercial water electrolysers2 and H2˙−O2 fuel cells limit their efficiencies to values well below those expected theoretically. The power loss of these devices is ≳15% even at low current densities, and much higher in practical operating conditions. We report here the preparation and the oxygen evolution reaction (OER) electrocatalytic properties of iridium oxide films deposited by reactively sputtering iridium in a humidified oxygen discharge. We find that these sputtered iridium oxide films (SIROFs) have catalytic properties far superior to the best known catalysts for oxygen evolution in acidic aqueous electrolytes at room temperature.
