Infrared spectroscopic study of isocyanate formation in the reaction of NO and CO over Cr2O3/Al2O3 and Cr2O3/SiO2

János Raskó  and  Frigyes Solymosi  

Abstract

The formation of an isocyanate complex in the NO + CO reaction on alumina- and silica-supported chromia was investigated by infrared spectroscopy. Isotopically-labelled gases were used to confirm that the bands at 2262 and 2242 cm–1 on Cr2O3/Al2O3 are due to surface isocyanate. The effects of the experimental conditions on the intensities of the above bands were investigated in detail. Isocyanate on Cr2O3/SiO2 yielded bands at 2315 and 2210 cm–1. The band at 2210 cm–1 was assigned to Cr2+–NCO, while the bands at 2262 and 2242 cm–1 and that at 2315 cm–1 were attributed to the isocyanate complex residing on alumina and silica, respectively.
