IR studies of the transformations of nitrogen-containing organic intermediates during selective reduction of nitrogen oxides by hydrocarbons

Abstract

Abs~a~Thermal transformations of nitromethane and deuterated acetonitrile adsorbed on the surface of H-ZSM-5, Cu-ZSM-5, Co-ZSM-5 has been studied by IR spectroscopy. The nature of cation has been found to greatly affect the transformation pathways of these species as possible intermediates in the NO~ selective reduction by hydrocarbons, thus explaining the different selectivities of these catalysts.
