摘　　要：采用原位漫反射傅利叶变换红外光谱(In-Situ DRFTIRS)研究一氧化氮在负载于氧化铈的四苯基卟啉钴(CoTPP-CeO_2)上的催化分解反应。考察了NO吸附态在表面分解反应中的反应性能,初步探讨了表面分解反应的机制和中间过渡态的结构。The study of catalystic decomposition reaction of nitric oxide on CoTPP-CeO2 was carried out by In-situ diffuse reflectance infrared spectioscopy (In-situ DRFTIRS). It was observed using rapid collection technique that the peak intensities of NO and N20 in gas phase and of adspecies of NO and N02 changed. Two types of NO adsorbed on surface at 1 816.7 and 1 696 .5 cm-1 was found at 250℃.Later has reaction activity for catalystic decomposition reaction of NO on surface. The reaction mechanism and the structure of reaction intermediate were discussed in this paper.
