The effect of Cu and Fe cations on NH3-supported proton transport in DeNOx-SCR zeolite catalysts

Author affiliations

Abstract

Proton transport studies revealed the different influence of Fe and Cu cations on the NH3–zeolite interaction and the NO–zeolite interaction in the presence of adsorbed NH3. At low temperatures, after NH3 saturation, Cu-ZSM-5 is more reactive than Fe-ZSM-5 for NO activation forming highly mobile NH4+ intermediates.
