Their properties were characterized by X-ray diffraction (XRD), NH<sub>3</sub> temperature-programmed desorption (NH<sub>3</sub>-TPD), H<sub>2</sub> temperature-programmed reduction (H<sub>2</sub>-TPR), N<sub>2</sub> adsorption/desorption, and CO-chemisorption. The catalytic activity and the resistance to water poisoning of the prepared Pd catalysts were tested in a simulated exhaust gas from lean-burn natural gas vehicles with and without water vapor. The results demonstrated that the modified supports had an apparent effect on the performance of Pd catalysts, compared with the Pd catalyst supported on the unmodified ZrAl. The addition of ZnO or Y<sub>2</sub>O<sub>3</sub> promoted the conversion of CH<sub>4</sub>. In the absence of water vapor, Pd/ZnZrAl exhibited the best activity for CH<sub>4</sub> conversion with the light-off temperature (<em>T</em><sub>50</sub>) of 275 °C and the complete conversion temperature (<em>T</em><sub>90</sub>) of 314 °C, respectively.
