Impregnation method prepared Cu-Co-Ce-O catalysts and their activities for low-temperature carbon monoxide oxidation
The support CeO2 was prepared by thermal decomposition method,and the Cu-Co-Ce-O catalysts were synthesized via impregnation method.The prepared catalysts were characterized by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR) techniques,and their catalytic properties for low-temperature CO oxidation were evaluated by using a microreactor-GC system.The results showed that the Co/Ce atomic ratio has great effect on the activities of catalysts,and the catalyst with Co/Ce =1 has the highest catalytic activity for CO total oxidation at 90 ℃.
