The catalytic activity for the oxidation of CO, reduction and desorptionrenewal properties of oxygen species on Pt/Al2O3 catalyst system doped with ZrO2 were studied by TPR, TPD-MS and flowing reaction methods. It was shown that ZrO2 could promote the desorption-renewal of oxygen species on catalysts and thus increase the oxidation activity of CO and H2-O2 reaction on such catalysts. These results were interpreted by the model of catalyst group structure correspondence.
