A series of CuSO₄/TiO₂ catalysts were prepared using a wet impregnation method. The activity of each sample in the selective catalytic reduction of NO by NH₃ (NH₃-SCR) was determined. The effects of SO₂ and H₂O, and their combined effect, on the activity were examined at 340℃ for 24 h. The catalysts were characterized using N₂ adsorption-desorption, X-ray diffraction, X-ray photoelectron spectroscopy, temperature-programmed reduction of H₂ (H₂-TPR), temperature-programmed desorption of NH₃ (NH₃-TPD), and in situ diffuse-reflectance infrared Fourier-transform spectroscopy (DRIFTS). The CuSO₄/TiO₂ catalysts had good activities, with low production of N₂O above 340℃. SO₂ or a combination of SO₂ and H₂O had little effect on the activity, and H₂O caused only a slight decrease in activity during the experimental period. The NH₃-TPD and H₂-TPR results showed that CuSO₄ increased the amounts of acid sites and adsorbed oxygen on the catalyst. In situ DRIFTS showed that the NH₃-SCR reaction on the CuSO₄/TiO₂ catalysts followed an Eley-Rideal mechanism. The reaction of gaseous NO with NH₃ adsorbed on Lewis acid sites to form N₂ and H₂O could be the main reaction pathway, and oxygen adsorption might favor this process.
