Amorphous CeO₂@TiO₂ catalyst was prepared by spontaneous deposition method and characterized by XRD, Raman spectra, TEM, N₂ physisorption, H₂-TPR, NH₃-TPD and FT-IR; its performance in the selective catalytic reduction (SCR) of NO with NH₃ was investigated. The results show that there is a strong interaction between Ce and Ti which are combined at atomic level. In comparison with the crystal CeO₂/TiO₂ catalyst prepared by impregnation, the amorphous CeO₂@TiO₂ catalyst exhibits larger surface area and pore volume, excellent redox ability and acidity, and outstanding catalytic performance in SCR. Over the CeO₂@TiO₂ catalyst, the conversion of NO reaches 80% at 175℃ and retains 96.0%-99.4% at 200-400℃. Moreover, the amorphous CeO₂@TiO₂ catalyst also shows strong resistance to H₂O and SO₂ poisoning.
