Abstract  

PdO/PdO/Ce1-xPdxO2-δ (PdO/CP) and PdO/Ce1-x-yPdxZryO2-δ (PdO/CPZ) catalysts were prepared via a solution combustion method. The corresponding PdO/Ce1-xPdxO2-δ (CP) and Ce1-x-yPdxZryO2-δ (CPZ) catalysts were obtained by nitric acid treatment of the PdO/CP and PdO/CPZ catalysts to remove the surface PdO species. These catalysts were tested for CO and CH4 catalytic oxidation. The turnover frequencies (TOFs) of surface PdO and Pdn+ cations in the CP and CPZ solid solutions were calculated. The results showed that Zr addition in the PdO/CP catalyst had very different effects on CO and CH4 oxidation. A significant improvement in CO oxidation activity was observed over the Zr-containing catalysts; this could be related to the formation of smaller PdO particles on the surface of the PdO/CPZ catalyst and a higher oxygen vacancy concentration in the CPZ solid solution. For CH4 oxidation, Pdn + cations in the solid solution play a key role in the catalytic oxidation process. The penetration of Zr4+ cations into the CeO2 lattice decreased the amount of Pd2+ cations in the CPZ solid solution and thus inhibited the activities of the Zr-containing catalysts (PdO/CPZ and CPZ) for CH4 oxidation.
