Oxygen Activation and Equilibration

Reliable information on oxygen activation could be obtained from the study of the 0/ 0 homoexchange reaction (or equilibration reaction) on supported metal catalysts. In fact, homoexchange is an overall measurement of the [Pg.262]

Relative Activities of Metals in the Oxygen Activation Process [Pg.262]

According to Table 7.6, the relative activities in the equilibration reaction at [Pg.262]

300°C of solids prepared using chlorine-free precursors would be Ru Rh Pt Pd. [Pg.262]

Additional measurements on a full series of ceria and cerium-zirconium mixed oxides supported noble metals showed that Ru was at least 10000 times more active than Pd and about 20 times more active than Rh for the activation of oxygen [70]. Up to now, most results were obtained with Rh catalysts but Ru could be a good candidate for surface diffusion measurements. [Pg.262]
