摘　　要：研究了轻稀土氧化物添加对Ｐｄ／γ－ＡＬ２Ｏ３催化剂活性的影响。实验表明，轻稀土氧化物的添加提高了单一钯催化剂对一氧化碳的氧化活性，尤以钕为最佳，其对ＣＯ的氧化温度（Ｔ５０％，Ｔ９０％和Ｔ９５％）都降低了５０℃之多。The influence of light rare earth oxides on the activity of Pd/Y-Al2O3 has been discussed in this. The test indicates that the activity of Pd/Y-Al2O3 for the oxidation of carbon monoxide increased by adding in rare earth oxides, especially Nd2O3. The conversion temperature. T50%, T90% and T95%, of this catalyst under addition are brought down about 50℃ as compared with that of the only Pd catalyst.
