研究了氧化铜的加入对锆铈复合氧化物的结构与性能的影响，发现氧化铜的加入可降低氧化铈的还原温度，稳定复合氧化物的立方结构，提高对CO氧化的催化活性。增加铈含量能提高催化剂的活性，而硫酸盐等可使催化剂的活性降低。掺铜锆铈复合氧化物催化剂的活性几乎不受高温灼烧的影响，是一种具有较高热稳定性的催化剂。

The effect of CuO on the structure and properties of zirconia-ceria mixed oxide was studied. The results show that addition of CuO decreases the reduction temp erature of ceria, stabilizes the cubic structure and enhances catalytic activity of CuO-ZrO2-CeO2 mixed oxides. Increasing ceria content in the mixed oxid es can enhance the catalytic activity, but some impurities such as sulfate make catalytic activity falling. There is little effect of calcination temperature on catalytic activities, implying that these catalysts are effective with good the rmal stability.
