| 英文摘要 | The effect of K deactivation on V2O5/WO3-TiO2 and Ce-doped V2O5/WO3-TiO2 catalysts in the selective catalytic reduction (SCR) of NOx by NH3 was studied. Ce-doped V2O5/WO3-TiO(2)showed significantly higher resistance to K deactivation than V2O5/WO3-TiO2. Ce-doped V2O5/WO3-TiO2 with K/V = 4 (molar ratio) showed 90% NOx conversion at 350 degrees C, whereas in this case V2O5/WO3-TiO2 showed no activity. The fresh and K-poisoned V2O5/WO3-TiO2 and Ce-doped V2O5/WO3-TiO(2 )catalysts were investigated by means of in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), NH3-temperature progress decomposition (NH3-TPD), X-ray photoelectron spectroscopy (XPS) and H-2-temperature program reduction (H-2-TPR). The effect of Ce doping on the improving resistance to K of V2O5/WO3-TiO2 were discussed. (C) 2018 The Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences.
