摘要：

以水滑石为前驱体,通过流电沉积法制备了Pt负载型催化剂。 在该催化剂中,贵金属Pt具有良好的分散性。 此外,以CO氧化为探针反应考查了不同Pt负载量对CO催化氧化性能的影响。 结果表明,当Pt的负载量为5%时,催化剂对CO的完全转化温度仅为90 ℃。

关键词: 水滑石, 铂, 流电沉积法, 一氧化碳氧化

Abstract:

A series of Pt supported catalysts was prepared by galvanic method with the precursor of hydrotalcite. Pt is well dispersed in the catalyst. Besides, CO oxidation was employed as a probe reaction and the performance of the catalysts with different Pt loading was studied. The results show that CO can be completely oxidized at 90 ℃ when the loading amount of Pt is 5%.

Key words: hydrotalcite, Pt, galvanic method, CO oxidation
