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

Proton transport studies revealed the different influence of Fe and Cu cations on the NH 3 -zeolite interaction and the NO-zeolite interaction in the presence of adsorbed NH 3 . At low temperatures, after NH 3 saturation, Cu-ZSM-5 is more reactive than Fe-ZSM-5 for NO activation forming highly mobil...

description Proton transport studies revealed the different influence of Fe and Cu cations on the NH 3 -zeolite interaction and the NO-zeolite interaction in the presence of adsorbed NH 3 . At low temperatures, after NH 3 saturation, Cu-ZSM-5 is more reactive than Fe-ZSM-5 for NO activation forming highly mobile NH 4 + intermediates. Proton transport studies revealed the different influence of Fe and Cu cations on the NH 3 -zeolite interaction and the NO-zeolite interaction in the presence of adsorbed NH 3 .
