摘要：
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.
