摘　　要：为提高V-W-Mo/TiO_(2)催化剂的宽温脱硝性能,采用堇青石对催化进行改性调控。采用XRD、N_(2)物理吸脱附、H_(2)-TPR等手段对改性催化剂进行了表征,添加堇青石可显著提高催化剂比表面积以及活性位点的还原性,有效增强催化剂脱硝活性。In order to improve the wide temperature denitrification performance of V-W-Mo/TiO_(2)catalyst,cordierite was used to modify the catalyst.The physicochemical properties of different catalysts were characterized by XRD,N_(2)adsorption-desorption and H_(2)-TPR.The results show that cordierite addition can significantly improve the specific surface area of catalysts and the reducibility of active sites,effectively enhancing the denitrification activity of catalysts.
