NO Reduction over Fe-Cu/ZSM-۵ Nanocatalyst and Study Catalyst Preparation Parameters

چکیده مقاله

Fe-Cu/ZSM-5 bimetal nanocatalyst was prepared by impregnation method and tested in SCR of NO with NH3 in the presence of oxygen. The results indicated that this nanocatalyst had high activity (67% at 250°C and 93% at 300°C) for NO conversion. The optimum preparation condition was obtained at 4.2 wt.% Fe loading, calcinations temperature of 577°C and impregnation temperature of 43.5°C. Under these conditions, NO conversion efficiency was 78.8% at 250°C.
