摘　　要：文章对不同温度焙烧的TiO2载体负载CuO催化剂的结构性能和催化活性进行了研究。XRD和Ra-man检测结果表明TiO2经600℃焙烧后,具有锐钛矿相和金红石相的混晶结构。600℃焙烧的TiO2负载6%CuO催化剂活性较高,反应温度375℃时,NO转化率达82.6%。TiO2负载CuO催化剂的表征结果说明,CuO与TiO2之间存在着较强的相互作用力。结合H2-TPR结果分析,表明催化剂表面的还原物种是CuO。This thesis studies the properties and activities of the CuO/TiO2 by TiO2 carrier calcined at different temperatures. Then, it investigates the anatase and rutile mixed-phases in TiO2 carrier calcined at 600℃ by XRD and carries out Raman analysis. The 6% of CuO/TiO2 studied when the TiO2 carrier cal- cines at 600℃ demonstrates better activities. NO conversion is 82. 6% at the reaction temperature of 375℃. All characteristics of the catalysts show CuO has strong interference with TiO2. Combined with the profiles of H2-TPR, it suggests reduction peaks are the reduction of CuO species.
