| Abstract: | Two types of catalysts with the same palladium loading, palladium-substituted perovskite La0.95Ce0.05Co0.95Pd0.05O3 and perovskite-supported palladium catalyst Pd/La0.95Ce0.05CoO3 were prepared by the combustion and impregnation method, respectively. The catalyst structure was characterized by X-ray diffraction (XRD), BET measurements, temperature-programmed reduction (TPR) and the methane oxidation activity of the catalysts were investigated in detail. It was found that the activity performance of Pd/La0.95Ce0.05CoO3 was higher than that of La0.95Ce0.05Co0.95Pd0.05O3, and this was owing to the ease of reduction of palladium in the former. |
