Description	Hexagonální mesoporézní siliky obsahující vanad byly připraveny přímou syntézou a impregnačním postupem v široké škále koncentrací (0.68 ? 7.8 wt. %). Výzkum distribuce komplexů vanadu pomocí H2-TPR prokázal, že přímá syntéza vede k přednostně k tvorbě materiálů s velice úzkou distribucí typů komplexů, zatímco impregnační postup vede ke vzniku oligomerických a oxidických komplexů se širokou škálou disperze. katalytické účinky materiálů získaných přímou syntézou byly výrazně lepší než chování impregnovaných materiálů. (cs) 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. The catalytic results in propane ODH were much better for synthesized catalysts compared to impregnated catalysts.
