Abstract

In the present work, fresh and Ca poisoned Fe–Ce/Ti catalysts were prepared and used for the NH3-SCR reaction to investigate the effect of Ca doping on the catalytic activity of catalysts. And these catalysts were characterized by BET, XRD, Raman, UV-vis DRS, XPS, H2-TPR, and NH3-TPD techniques. The obtained results demonstrate that Ca doping could lead to an obvious decrease in the catalytic activity of catalysts. The reasons for this may be due to the smaller specific surface area and pore volume, the decreased ratio of Fe3+/Fe2+ and Ce3+/Ce4+, as well as the reduced redox ability and surface acidity.
