铈锆复合氧化物催化剂的储放氧能力和高温稳定性

Oxygen Storage Capacity and High Temperature Stability of Composite Ceria-Zirconia for Catalyst Preparation

介绍了用独特工艺制备的单一立方相铈锆复合氧化物的储放氧能力、高温稳定性、X射线衍射图谱和晶格常数以及净化 CO、C3H6 和 NO的起燃温度 ,并与 Ce O2 催化剂进行了比较。

The features of specially prepared cubic composite oxide of ceria-zirconia have been discussed with respect to oxygen storage capacity,thermal stability,X-ray diffraction data,crystal lattice parameters as well as its light-off temperature for the conversion of CO,C 3H 6 and NO in comparison with pure ceria,the former has been shown to be much superior to the latter.
