摘要: Abstract Cu-cations were exchanged into BEA and FER zeolites at different Cu/Al ratios the resulting materials studied for selective catalytic reduction (SCR) of NO with NH 3 . Higher had more reducible during temperature-programmed (TPR) H 2 , also lead to higher activity -SCR NO. This indicates that ease undergoing redox cycles is important SCR activity, in particular ability oxidize low temperatures. In study pore sizes do not seem play a major role SCR, but structure seems determining speciation hence their redox-activity.
