摘要：
A series of MoO3 doped Fe2O3 catalysts prepared by the co-precipitation method were investigated in the selective catalytic reduction of NO by NH3 (NH3-SCR). The catalysts displayed excellent catalytic activity from 225 to 400°C and high tolerance to SO2/H2O poisoning at 300°C. To characterize the catalysts the N2-BET, XRD, Raman, NO-TPD, NH3-TPD and in situ DRIFTS were carried out. It was found that the main reason explaining a high NH3-SCR performance might be the synergistic effect between Fe and Mo species in the catalyst that could enhance the dispersion of Fe2O3 and increase NH3 adsorption on the catalyst surface.
