Abstract:

CeO2-Fe3O4/TiO2 and CeO2/TiO2 catalysts were prepared by coprecipitation method, and their activities for selective catalytic reduction of NO with NH3 were investigated. As can be seen from the experimental results, the CeO2-Fe3O4/TiO2 catalyst prepared showed the best SCR activity and SO2 resistance. Based on the characterization results of BET, XRD, NH3-TPD and XPS the excellent performance of CeO2-Fe3O4/TiO2 catalyst should be resulted from its large surface area, high NH3 adsorption capacity and high concentration of surface chemisorbed oxygen.
