| Abstract: | DeNOx SCR catalysts with Pt were prepared using V2O5 and WO3 as the active components and anatase titania as the support, and adding micro component Pt. The as-prepared catalyst was characterized by BET and XRD, and its denitrification performance was investigated. The results showed that the specific surface area, light-off temperature and the temperature window of the catalyst had certain change The catalyst exhibited better catalytic activity and stable denitrification rate of over 90% under the condition of 160 ℃ and NH3/NOx volume ratio 0.8 - 1.2. |
