摘要：

Catalytic oxidation is an efficient way to convert CO to CO2 at low temperature. Precious metal catalysts such as Ft and Pd have been demonstrated to be very effective[1]. However, attention has also been given to base metals due to the limited availability of precious metals. As a single component base metal catalyst cannot rival a precious metal catalyst, improvement in its activity has been attempted by combining several elements[2,3]. In the present work, we studied redox and structure of Ag-M(M=Mn、Ce and Cu) catalysts to gain some evidence of the synergism between Ag and base metals, and investigated their catalytic activities.
