摘要

Fe-Mn/ETS-10 catalysts with various compositions were synthesized by high temperature solid state reaction. These catalysts were characterized by X-ray diffractometry(XRD), Fourier transform infrared spectroscopy(IR), scanning electron microscopy(SEM) and X-ray photoelectron spectroscopy(XPS). The effect of different amounts of Fe-Mn/ETS-10 on the morphology, composition and the catalytic reduction performance was studied. The results show that Fe-Mn/ETS-10 has good uniformity and dispersion, the morphology and crystal structure of ETS-10 are kept. 5%Fe-1%Mn/ETS-10 has more active sites and higher deNOx performance. The catalysts activity of CO-SCR results show that denitrification rates of 5%Fe-1%Mn/ETS-10 are 80% and 85% at 300℃ and 400℃, respectively. So, it is concluded that an optimal Fe-Mn/ETS-10 catalyst support ratio (5%Fe-1%Mn/ETS-10) enhances the catalytic activity in the selective catalytic reduction reaction.
