Abstract

An environmentally benign Fe-Ce-Ti mixed oxide catalyst, which was prepared via the hydrothermal method, has been investigated for the selective catalytic reduction of NO_x with NH₃ (NH₃-SCR). It was found that the Fe-Ce-Ti catalyst exhibited excellent NH₃-SCR activity, high N₂ selectivity and strong resistance against H₂O and SO₂ with a wide operation temperature window. XRD and Raman spectra suggest that the Fe-Ce-Ti catalyst has an amorphous structure. The co-presence of Fe and Ce induced the formation of a redox cycle (Ce⁴⁺ + Fe²⁺ ↔ Ce³⁺ + Fe³⁺), which promotes the activation of NO and NH₃. In situ DRIFTS studies demonstrate that the synergetic effect between Fe and Ce contributes to the formation of reactive intermediate species, thus leading to the high catalytic deNO_x performance of the Fe-Ce-Ti mixed oxide catalyst.
