The transition metals (i.e., Co, Mn) supported rod-like CeO2 nanomaterials with different proportions were prepared by an one-step hydrothermal method. The influence of transition metals (Co, Mn) content on the crystal lattice constant, element content of different valence states of the catalyst, specific surface area and CO catalytic oxidation performance were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, X-ray photoelectron microscopy, specific surface area analysis, H2-temperature programmed reduction and CO-temperature programmed desorption, respectively. In addition, compared to pure CeO2, CeO2 nanorods supported Co or Mn show a greater catalytic activity for CO at a low temperature. The temperature range of Co-CeO2 with catalytic oxidation CO of 50% (T50%) is 97-133℃, and that of Mn-CeO2 is 107-195℃. Co-CeO2 and Mn-CeO2 with 40% (in mole fraction) of Co or Mn show the optimum catalytic performance, and the T50% of 40% Co-CeO2 is 97℃ and 40% Mn-CeO2 is 107℃, respectively. The introduction of transition metal (Co, Mn) enhances the synergistic effect on the catalyst surface and produced more active oxygen, thus effectively enhancing the catalytic oxidation performance of the nanomaterials.
