| 摘 要： | 用流动反应法、TPR和TPD－MS等技术研究了Pt／Al2O3催化剂掺杂ZrO2体系上CO的催化氧化反应、氧物种的还原及脱出－恢复行为．结果表明，掺杂ZrO2有利于催化剂上氧物种的脱出－恢复，从而促进CO氧化活性及表面活泼氧物种与氢的反应．并用催化剂集团结构适应理论对结果作出了解释．

| Abstract: | 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. |
