| 摘 要： | 对几种钛基复合氧化物负载的ＣｕＯ催化剂的ＣＯ氧化催化性能进行了初步探讨。结果发现，添加不同的金属氧化物导致催化剂的活性不同。Ａｌ２Ｏ３的加入，抑制了反应的进行；ＺｒＯ２的加入，对催化剂的活性影响不大；ＳｎＯ２和ＣｅＯ２的添加则有效地促进了该反应的进行。此外，采用不同制备方法得到的催化剂的催化活性也都不同，利用浸渍法制备的催化剂均比共沉淀法得到的催化剂的催化活性高。

| Abstract: | Several CuO catalysts supported on different composite titania based oxides are prepared and tested for their catalytic activities in CO oxidation using a mixture of carbon monoxide and air as feed. Effects of different metal oxides added to the titania based support are investigation on catalytic activities of the catalysts for CO oxidation. The results shaw that the reaction is promoted effectively by addition of SnO 2 and CeO 2, while inhibited by that of Al 2O 3. Addition of ZrO 2 has no significant effect on activity. Moreover, the catalysts prepared by impregnation are more active than those by coprecipitation. |
