In this paper, oxidation activity of CuO/γ-A12O3 catalysts and the addition of CeO2 on CuO/γ-A12O3 catalysts for oxidation reaction of n-hexane (n-C6H14 ) and carbon monoxide (CO ) were studied by means of the flow method techniques, XRD and TPD-MS. Experimental results indicated that (1) the addition of CeO2 improving disperse degree of CuO on CuO/γ-Al2O3 catalysts which caused a large increase in activity; (2) the addition of CeO2 may increase oxygen supplying ability and oxygen recovery ability of catalyst surface.
