| 摘 要： | 采用浸渍法制备负载型铂-钯催化剂,比较详尽的考察了制备条件对其催化CO氧化活性的影响.结果表明:常温浸渍、陈化时间大于5 h、H2还原制得的催化剂,具有很好的低温活性和抗湿性.在相对湿度大于90%和空气中含100 ppm CO的条件下,Pt、Pd含量均为0.3%的催化剂在1 h内对CO的常温消除效率高于90%.

| Abstract: | Supported Pt-Pd Catalysts were prepared by impregnation,and the effects of preparation conditions on catalytic performance for CO oxidation over these catalysts were studied in detail.It was found that,the Pt-Pd Catalyst prepared by normal temperature impregnation,impregnating-time >5 h,reduced by H2,exhibited best low temperature activity and resistance to moisture.Under the conditions of relative humidity >90% and 100 ppm CO in air,the average CO conversion of 0.3%Pt-0.3%Pd catalyst at room temperature was higher than 90% in 1 h. |
