Abstract Mn-WO 3 /TiO 2 catalysts were investigated for Selective Catalytic Reduction (SCR) of NO with NH . The synthesized by wetness impregnation method different Mn loadings (1.5-3-12 wt%) on 8wt%WO All three compared and bare MnO x oxide, used as references. 1.5wt%Mn-8wt%WO exhibited the highest performance in conversion N selectivity. A commercial catalyst, based titania supported vanadia ...

The physical, electronic and reactivity properties of bulk and supported Group V metal oxides (V, Nb, Ta and Db) were compared at the molecular level. Dubnium is a very short-lived element, ∼60 s, whose properties have not been extensively studied, but can be predicted from knowledge of the other members of the Group V metal oxides. Bulk V2O5 possesses platelet morphology with the active surfac...

The effect of the addition of V2O5 on the structure, sintering and dielectric properties of M-phase (Li1+xyNb1-x-3yTix+4y)O3 ceramics has been investigated. Homogeneous substitution of V5+ for Nb5+ was obtained in LiNb0.6(1-x) V0.6xTi0.5O3 for x ≤ 0.02. The addition of V2O5 led to a large reduction in the sintering temperature and samples with x = 0.02 could be fully densified at 900oC. The sub...
