The Zn-Co complex oxides were prepared by the method of coprecipitation. The effect of adding K^+ and Al^3^+ on these oxides was investigated. According to the Rietveld structure Refinement of powder X-ray diffraction, it is found that the addition of K^+ and Al^3^+ produces opposite effect on the oxygen parameter of the spinels. The results of the TPR、TPD-MS and CO oxidation show that the addition of K^+ promotes the catalytic oxidation activity of Zn-Co complex oxide, but Al^3^+ refrains the catalytic oxidation activity. The influence of addition of K^+ and Al^3^+ on the oxygen parameters may be related to the oxidation activities closely.
