摘　　要：本文考察了γ-Al_2O_3负载Cu-Ag的双金属及其单金属催化剂对苯和丙酮的氧化活性以及热处理温度对其结构和催化氧化活性的影响.结果表明,少量Ag的添加能明显提高催化剂对苯和丙酮的完全氧化活性,其活性大小次序为:Cu-Ag/γ-Al_2O_3>Cu/γ-Al_2O_3>Ag/γ-Al_2O_3.同时还发现,热处理温度对催化剂的结构和氧化活性有明显的影响,Ag的存在,在一定程度上提高了催化剂的热稳定性.The activity of the y-Al2O3-supported Cu-Ag bimetallic and the individual mono-metallic catalysts, and the effect of thermal treatment on the stucture and the catalytic oxidation activity of these catalysts have been investigated. It was found that the activity of catalyst for benzene and acetone oxidation was enhanced with the addition of Ag. The order of activity was : Cu-Ag/γ-Al2O3>Cu/γ-Al2O3>Ag/γ-Al2O3. The results showed that the structure and the oxidation activity of the catalysts were affected by the treatment temperature. The addition of Ag improved the thermal stability of the catalyst.
