Effect of synthesis methods on activity of V 2 O 5 /CeO 2 /W

发布时间：2021-06-13 07:06

　　The effect of synthesis methods on the activity of V/Ce/WTi catalysts was investigated for the selective catalytic reduction（SCR） of NO_x by NH₃. V/Ce/WTi-DP（deposition precipitation） catalyst showed excellent NH₃-SCR performance, especially the better medium-temperature activity and the less N₂O formation than V/Ce/WTi-IMP（impregnation）. These catalysts were characterized by X-ray diffraction（XRD）, Brumauer-Emmett-Teller（BET）, X-ray photoelectron spect...
