用ＴＰＤ－ＭＳ、ＴＰＳＲ－ＭＳ及ＣＯ氧化活性测定等方法研究了Ｐｔ／Ａｌ２Ｏ３和掺杂超细ＺｒＯ２的样品的表面氧脱出－恢复性能、ＣＯ表面氧化性能及催化氧化性能．结果表明，在Ｐｔ／Ａｌ２Ｏ３中掺杂ＺｒＯ２后，样品表面上的氧物种脱出和氧化恢复性能明显提高，脱氧量也明显增大；并发现在ＣＯ－ＴＰＳＲ过程中程脱物ＣＯ２的脱附量大小及峰顶温度次序与对ＣＯ的催化氧化活性也有一致的关系 The surface oxygen removal-recovery performance, CO surface oxidation performance and catalytic oxidation performance of Pt / Al2O3 and ZrO2-doped samples were investigated by TPD-MS, TPSR-MS and CO oxidation assay. The results show that after the ZrO2 is doped in Pt / Al2O3, the oxygen species outgrowth and the oxidative recovery performance of the sample surface are obviously increased and the amount of deoxygenation is obviously increased. It is also found that the desorption amount of CO2 in the process of CO-TPSR And peak temperature order and the catalytic activity of CO oxidation also have a consistent relationship
