Ti0.99Pd0.01O(2-delta): a new Pt-free catalyst for high rates of H2 + O2 recombination with high CO tolerant capacity.
A platinum-free H(2)/O(2) recombination catalyst, Ti(0.99)Pd(0.01)O(2-delta), is synthesized by a solution combustion method where Pd(2+) ions adsorb protonic H(2)(delta+) ion and oxygen on the oxide ion vacancy sites (see picture). The rate of H(2) + O(2) recombination at 50 degrees C is 15 micromoles g(-1) s(-1), which is much higher than that of Pt-containing catalysts.
