摘要: 采用浸渍法制备了Co/CeO2和Co/TiO2催化剂，考察了Co/CeO2和Co/TiO2催化剂催化燃烧甲苯的催化行为。研究表明：Co/CeO2催化剂活性高于Co/TiO2催化剂活性。Co/CeO2催化剂具有较低的起燃温度(T50 = 210℃)，同时其在225℃下甲苯的转化效率可稳定在80%。Co/CeO2具有更大的比表面积，可增加反应物与催化剂的接触面积，提高催化剂活性。Co/CeO2和Co/TiO2催化剂中活性组分主要为Co3O4。Co/CeO2催化剂表面含有较高含量的Osurf和Co3O4可能是Co/CeO2催化剂具有更高活性的原因。
Abstract: Co/CeO2 and Co/TiO2 catalysts were prepared by impregnation method. The catalytic behavior of Co/CeO2 and Co/TiO2 catalysts for catalytic combustion of toluene was investigated. It shows that the activity of Co/CeO2 catalyst is higher than that of Co/TiO2 catalyst. Co/CeO2 catalyst has a lower light-off temperature (T50 = 210˚C), while the conversion of toluene can be stabilized at 80% at 225˚C on Co/CeO2. Co/CeO2 has a larger specific surface area, which increases the contact area of the reactants with the catalyst, resulting in the higher activity of the catalyst. The active component in the Co/CeO2 and Co/TiO2 catalysts is Co3O4. The higher content of Osurf and Co3O4 on the surface of Co/CeO2 catalyst may be the main reason for the higher activity of Co/CeO2 catalyst.
