摘要：

In this work, various supported platinum catalysts (Pt/MeOx, Me = Fe, Zn, Al, Ni) were prepared by colloid-deposition method, and their catalytic properties for the low-temperature CO oxidation were investigated. It was found that the type of support has considerable effect on the activity of the catalysts. The addition of water vapor in feed stream has the positive influence on the activity of the catalysts. Under an optimized tested condition, Pt/Fe2O3 shows unusual low-temperature activity and long-term stability, and it can completely transform CO into CO2 at room temperature in the presence of water vapor for more than 3000 h.
