Abstract: 
The effect of addition of ruthenium to different CexZr1−xO2 (0 ≤ x ≤ 1) supports on the oxidation of propylene and carbon black (CB) was investigated. The results showed that different reactive ruthenium oxide species are formed following calcination at 600 °C. The reactivity increases with the cerium content in the support, Ru/CeO2 being the most reactive catalyst. However, the Ce0.5Zr0.5O2 support and corresponding catalyst, Ru/Ce0.5Zr0.5O2, exhibited decreased reactivities comparing to solids with lower cerium content. This was ascribed to the formation of a solid structure that inhibits the interaction between cerium and ruthenium oxide species following impregnation.
