| 摘 要： | 采用溶胶凝胶法制备了Cu／SiO2催化荆，用浸渍法将Mg元素担载在Cu／SiO2催化荆制得Mg-Cu／SiO2催化荆，研究在NO＋CO反应中的催化活性．结果表明，Mg修饰的采用方法（c）制备的Cu／SiO2催化荆，当Cu的含量是载体SiO2质量的2％，Mg的含量是载体SiO2质量的3％时，Mg-Cu／SiO2催化荆活性最高，250℃时NO生成N2的转化率接近100％．

| Abstract: | A series of Cu/SiO2 and Mg - Cu/SiO2 catalysts were prepared by different Sol - gel （ Cu （ NO3 ） 2 - Si （OR） 4 ） method and impregnation （ Mg（ NO3 ） 2 ） method. Based on the experimental results of activity e- valuation, the catalytic performances of catalysts for NO ＋ CO reaction were investigated. The results indi- cated that among Mg - Cu/Si02 （c） catalysts, the optimum loading amount of Mg and Cu were 3% and 2% respectively. The conversion of NO to N2 over Mg - Cu/Si02 catalyst was 100% at 250℃, GHSV 34000-1 h. |
