Effect of metal oxide partial substitution of V2O5 in V2O5–WO3/TiO2 on selective catalytic reduction of NO with NH3

After partial substitution of V2O5 in V2O5–WO3/TiO2 by metal oxide (MxOy, M=Fe, Co, Ni, Cu, Sr, La, and Ce), the NO conversions for the MxOy–V2O5–WO3/TiO2 catalysts (M-VW) showed the following sequence: Co–VW>Fe–VW>Sr-VW≈Ce-VW≈La-VW>VW>Ni-VW>Cu-VW. The reduction activities for almost...

Description
Summary:After partial substitution of V2O5 in V2O5–WO3/TiO2 by metal oxide (MxOy, M=Fe, Co, Ni, Cu, Sr, La, and Ce), the NO conversions for the MxOy–V2O5–WO3/TiO2 catalysts (M-VW) showed the following sequence: Co–VW>Fe–VW>Sr-VW≈Ce-VW≈La-VW>VW>Ni-VW>Cu-VW. The reduction activities for almost all the M-VW catalysts were enhanced at reaction temperature >400°C, but only the Co-VW catalyst showed an increased activity at temperature
