| Abstract | |
| A set of single metal oxides (CeO2, ZrO2, PrO2, CuO and Fe2O3) and binary oxide catalysts (Ce80Zr20, Ce80Pr20, Ce80Cu20 and Ce80Fe20) prepared by the solution combustion synthesis was tested for the CO oxidation reaction. As a whole, the best catalytic activity was achieved for the Ce80Cu20 catalyst (binary oxide with Ce = 80 at.% and Cu = 20 at.%).This confirms that CeOx and CuOx phases may cooperate effectively for this oxidation process. The easier surface reducibility of this catalyst should promote the CO oxidation reaction. Likewise, it appears that the presence of metals, such as the Cu, Zr, Fe and Pr, into the ceria framework has a beneficial effect on the CO oxidation via cooperative phenomena among the redox active centres. All the prepared catalysts were characterized by the powder XRD, FE-SEM, N2 physisorption at -196 °C and H2-TPR analysis. | |
