Polymer electrolyte water electrolysis is a promising technology for clean hydrogen production, but high-performance catalysts that can withstand the harsh anodic conditions are lacking. Now, mass-selected iridium-tantalum oxides are shown to have high catalytic activity and stability towards the oxygen evolution reaction under such conditions.
