Origin of the High Activity and Stability of Co3O4 in Low-temperature CO Oxidation
In this paper, the Co 3 O 4 catalysts prepared by the liquid phase precipitation method were investigated with respect to their activity and stability in CO oxidation reaction. The Co 3 O 4 catalysts were comparatively investigated by thermal gravimetry analysis (TG-DTG), X-ray powder diffraction (X...

catalysts prepared by the liquid phase precipitation method were investigated with respect to their activity and stability in CO oxidation reaction. The Co

O
4
catalysts were comparatively investigated by thermal gravimetry analysis (TG-DTG), X-ray powder diffraction (XRD), N
2
adsorption, CO titration and O
2
-temperature program desorption (O
2
-TPD). The results of XRD show that all the catalysts exist as a pure Co
3
O
4
phase with the spinel structure. The high catalytic activity observed at ambient temperature is followed by a gradual decrease. The CO titration experiments show that the Co
3
O
4
catalysts possess active oxygen species. The total amount of active oxygen species and the specific surface area decrease with increasing calcination temperature. The O
2
-TPD results indicate that O
2
−
and O
−
are the possible active oxygen species. |
