摘　　要：纳米Ag催化剂由于具有独特的物理和化学性质,在很多反应中受到了越来越多的关注,尤其对低温催化一氧化碳氧化反应.近年来,银催化剂表现出较高的催化活性、稳定性以及良好的应用前景,能够在常温下将CO氧化为CO2.本文结合本课题组的研究进展,从制备方法、载体、预处理、第二组分、其它气氛和催化反应机理等方面对Ag基催化剂上CO氧化反应进行了系统的讨论和总结.Nanosized Ag catalysts have attracted much attention because of their unique catalytic properties for various reactions, in particular for CO oxidation at low temperatures. Recently, Ag catalysts displaying high catalytic activities and reaction stabilities, and good application prospects in the elimination of CO, even at ambient temperature, have been developed. In this review, combined with our group’s research, the different influencing factors such as the preparation method, support, pretreatment conditions, second component, other atmosphere, and reaction mechanisms are discussed in detail and summarized.
