本研究以碳化硅为载体，Pt为活性组分，通过浸渍法制备了一系列的Pt/SiC催化剂,并考察了焙烧温度、空燃比、空速以及CeO2改性的Pt负载量对Pt/SiC催化剂的活性的影响。实验结果表明：在焙烧温度为500℃，CO:O2物质的量比为1:1.25,气体空速为900ml•min-1•g-1,Pt的负载量为3wt%时，Pt/SiC催化剂呈现出良好的CO催化氧化活性，CO氧化的最低转化温度为194℃。

This research take the silicon carbide as the carrier, Pt is theactive constituent, has prepared a series of Pt/SiC catalyst throughthe impregnation method, and inspected the roasting temperature, hasspatially burnt the ratio, the airspeed as well as CeO2 modified Pt负载量 to the Pt/SiC catalyst active influence. The experimentalresult indicated that, In the roasting temperature is 500 ℃, whenthe CO:O2 matter quantity compared to is 1:1.25, gas airspeed is900mlmin-1g-1, Pt 负载量 is 3wt%, the Pt/SiC catalyst presents thegood CO catalyzed oxidation activeness, the CO oxidation lowestinversion temperature is 194 ℃.
