Abstract
A simple and versatile strategy of catalytic promotion is presented that is able to significantly improve both the catalytic propane combustion and most notably the oxygen evolution reaction activity in acidic water electrolysis of phase-pure Ir0.3Ti0.7O2 by hydrogen incorporation of 26 at% into Ir0.3Ti0.7O2 through H2 exposure at 150 degrees C without compromising the long-term stability. The most attractive feature of hydrogen promotion is the prospect of improving oxidation catalysis for an entire class of materials, namely, mixed oxides, and for various oxidation reactions, regardless of whether they belong to thermal or electrocatalysis. Hydrogen promotion is proposed to be routinely tested in materials screening of mixed oxides in oxidation catalyts.
