| 摘 要： | 采用固相化学反应法制备了一系列CuO-CeO_2催化剂,并用X-射线衍射(XRD)、程序升温还原(H_2-TPR)和氮吸附等技术对样品进行了表征,利用微反-色谱装置考察了其催化CO低温氧化反应的活性,研究了CuO含量和催化剂焙烧温度对CuO-CeO_2催化活性的影响。结果表明,随着CuO含量的增加,CuO-CeO_2的催化活性提高,至不小于15%时达到稳定;随焙烧温度的升高,CuO-CeO_2的催化活性先提高,至650℃时达到最大,之后又降低。CuO-CeO_2的催化活性与其CuO的还原性之间有较好的对应关系。 |

| Abstract: | A series of CuO-CeO_2 catalysts were prepared by solid-state chemical reaction and characterized by X-ray diffraction(XRD),temperature-programmed reduction with hydrogen(H_2-TPR) and N_2 adsorption-desorption techniques.Their catalytic performances for low temperature oxidation of CO were evaluated by using a microreactor-GC system.The effects of CuO content and catalyst calcination temperature on the performance of the CuO-CeO_2 catalysts were investigated.The results show that the catalytic activity of th... |
