通过研究催化剂 Au/Ce0.6 Zr0.35 Y0.05 O2(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。% By the study of the catalytic activation energy of Au /Ce0.6 Zr0.35 Y0.05 O2 (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.
