摘要
A series of catalysts La0.95Ce0.05CoO3, La0.95Ce0.05Co0.95Pt0.05O3 and Pt/La0.95Ce0.05CoO3 were prepared by combustion method and impregnation method, respectively. The purpose of the present work was to study the effect of platinum, with the same loading, on the platinum-substituted perovskite and perovskite-supported platinum catalyst. The catalysts structure were characterized by X-ray diffraction (XRD), BET measurements, transmission electron micrographs (TEM) and the methane oxidation activity of the catalysts were investigated in detail. It was found that the catalytic activity of La0.95Ce0.05Co0.95Pt0.05O3 was superior to that of La0.95Ce0.05CoO3 and the activity performance of Pt/La0.95Ce0.05CoO3 was higher than that of La0.95Ce0.05Co0.95Pt0.05O3 for methane combustion.
