【Abstract】

<正> The effects of Pd loading, cerium content, the special surface area of the support and calcination temperature on the catalytic properties of Pd-loaded zirconia-ceria mixed oxide were studied. The results show that loading Pd and increasing cerium content in the mixed oxides can enhance the catalytic activity. There is a little effect of calcination temperature on catalytic activities, implying that these catalysts are effective with good thermal stability.
