DOI: 10.1016/j.jes.2019.12.002
Abstract: F-V2O5-WO3/TiO2 catalysts were prepared by the impregnation method. As the content of F ions increased from 0.00 to 0.35 wt.%, the NO conversion of F-V2O5-WO3/TiO2 catalysts initially increased and then decreased. The 0.2F-V2O5-WO3/TiO2 catalyst (0.2 wt.% F… read more here.
