| 摘 要： | 选用丙酮，乙醇、水、乙酸等4种不同溶剂，采用浸渍法制备Pt-K/Al2O3催化剂，电镜分析表明，Pt的分布，分散度与溶剂存在一定关系，且由于助剂K的添加，使Pt浓度的最大值并不在外表面，而在外表面之下；Pt-K/Al2O3的催化性能与Pt的分布，分散度及Pt/K比值有一定关系，当以乙醇为浸渍溶剂时，制备得到的催化剂催化性能最好。

| Abstract: | Several Pt\|K/Al\-2O\-3 catalysts prepared by using different impregnation solvents were studied. The solvents used were acetone? ethanol? water and acetic acid. Results obtained by electron microscope and H\-2\|O\-2 titration indicate that the distribution and dispersity of Pt on the support are closely related to the impregnation solvents. The maximum concentration of Pt is not on paricle surface due to the addition of K. The catalytic performance of Pt\|K/Al\-2O\-3 is affected by the distribution and dispersity of Pt and the ratio of Pt/K. Among the four solvents ethanol is the best one. |
