%X V2O5-MoO3/ TiO2 catalyst was prepared by sol-gel and impregnation method and modified with SiO2 to improve its alkali-resistant performance.The alkali poisoning was simulated by the immersion of the catalyst in alkali salt solution.The effect of SiO2 modification on the de-NOx activity of V2O5-MoO3/ TiO2 catalyst in the selective catalytic reduction was investigated.BET,H2-TPR and NH3-TPD measurements indicated that the specific surface area,the redox ability(the reduction temperature is decreased by 10 ℃) and the acidity of the SiO2-modified V2O5-MoO3/TiO2catalyst are increased obviously.As a result,the alkali-resistant performance of V2O5-MoO3/ TiO2 catalyst was improved largely by the SiO2 modification.
