Abstract:
A platinum‐free H 2 /O 2 recombination catalyst , Ti0.99Pd0.01O2?δ, is synthesized by a solution combustion method where Pd2+ ions adsorb protonic H2δ+ ion and oxygen on the oxide ion vacancy sites (see picture). The rate of H2+O2 recombination at 50 °C is 15 μmoles g?1 s?1, which is much higher than that of Pt‐containing catalysts.
