摘要：
The infrared spectrum in situ was used to study the mechanism of selective reduction of nitrogen oxides on a series of oxide catalysts. It is shown that under the reaction conditions, nitrites, nitrates, and nitroorganic and acetate complexes are formed. Qualitative comparison of the rate of decomposition of the complexes and the rate of formation of the process products was performed using the spectral kinetic technique. Based on this comparison, the role of surface complexes in the process was determined. A mechanism showing the main stages of the reduction of nitrogen oxides is proposed.
