"V-containing hexagonal mesoporous silica catalysts were prepared by direct synthesis and impregnation method in a wide range of V loading (0.68 ? 7.8 wt. %). Investigation of VOx complex distribution by means of H2-TPR reveals that direct synthesis method led predominantly to formation of material with very narrow distribution of VOx complexes, whereas impregnation methods resulted in materials with broad distribution of VOx species including VOx units with a lower degree of dispersion.
