【Abstract】 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.更多还原
