Hydrogen Incorporation in Ru<sub>x</sub>Ti<sub>1−x</sub>O<sub>2</sub> Mixed Oxides Promotes Total Oxidation of Propane

A rational synthetic approach is introduced to enable hydrogen insertion into oxides by forming a solid solution of a reducible oxide with a less reducible oxide as exemplified with RuO<sub>2</sub> and TiO<sub>2</sub> (Ru_x, a mixture of x% RuO<sub>2</sub> with (1...

description A rational synthetic approach is introduced to enable hydrogen insertion into oxides by forming a solid solution of a reducible oxide with a less reducible oxide as exemplified with RuO<sub>2</sub> and TiO<sub>2</sub> (Ru_x, a mixture of x% RuO<sub>2</sub> with (100−x)% TiO<sub>2</sub>). Hydrogen exposure at 250 °C to Ru_x (Ru_x_250R) results in substantial hydrogen incorporation accompanied by lattice strain that in turn induces pronounced activity variations. Here, we demonstrate that hydrogen incorporation in mixed oxides promotes the oxidation catalysis of propane combustion with Ru_60_250R being the catalytically most active catalyst.
