| 摘 要： | 助剂对铑催化一氧化碳加氢有很大影响,由于助剂有时会附在高表面积的担体上,而不是附在金属晶体上,从而削弱了助剂的作用。为提高助剂的分散度,Andersont等将含主、助剂金属元素的混合羰基簇化物浸渍到载体上,取得了较好的效果。但该法受到主、助剂原子

| Abstract: | A series of Rh-Ti/SiO2 catalysts were prepared by vapor deposition method. The catalysts were characterized by XPS, TPD and their activities of CO hydrogenation were tested in a microreactor system. The results show that the Ti content of the catalysts has approximately linear relations with the deposition time of TiCl4. Although Ti covers some of the active sites on the catalysts surface, it enhances the activity of each active site and the total activities. |
