中文摘要：

通过研究催化剂Au/Ce0.6Zr0.35Y0.05O2（Au/CZY）的活化能,以及对煅烧温度和催化剂活性的关系研究,揭示了负载金催化剂Au/CZY比纯CZY及Au/CeO2具有更高的一氧化碳氧化活性的原因是Au/CZY催化剂具有较低的活化能和较大的比表面积。

英文摘要：

By the study of the catalytic activation energy of Au/Ce0.6Zr0.35Y0.05O2（Au/CZY）, as well as the relationship of calcined temperature and catalyst activity, it is revealed that the catalytic activity of Au/CZY for CO oxidation is higher than those of the pure CZY and Au/CeO2, it is due to the lower activation energy and larger specific surface area for Au / CZY.
