本文研究了CO常温氧化的催化剂——MnO_2·CuO/Al_2O_3。考察了活性组分MnO_2,CuO的相对百分含量,浸渍溶液的酸度、焙烧温度、反应温度等因素对催化剂活性的影响。发现催化剂的活性与其差热分析的脱水峰及分解反应(MnO_2→Mn_2O_3)的峰温存在一定的对应关系。 In this paper, the catalysts for the oxidation of CO at room temperature - MnO 2. CuO / Al 2 O 3 are studied. The effects of factors such as the relative percentage of MnO 2 and CuO, the acidity of the impregnation solution, the calcination temperature and the reaction temperature on the catalytic activity were investigated. It is found that there is a certain correspondence between the activity of the catalyst and the peak temperature of its differential thermal analysis and the peak temperature of the decomposition reaction (MnO 2 → Mn 2 O 3).
