Description	HDS catalysts were prepared by loading H3PMo12O40 or H4PMo11V1O40 polyoxometallates on TiO2. Activity of the catalysts was tested in the HDS of thiophene. The activity of catalysts of low concentration was 2–3 times higher than the activity of those of high concentration. TPR measurements proved that vanadium promotes and stabilizes HDS activity due to an increase in the Mo5+/Mo4+ ratio.

(en) HDS katalyzátory byly připraveny nanášením H3PMo12O40 nebo H4PMo11V1O40 polyoxometalátů na TiO2. Jejich katalytická aktivita byla zjišťována u HDS thiofenu. Aktivita katalyzátorů obsahujících nízkou koncentraci Mo byla 2-3 krát vyšší než aktivita katalyzátorů s vysokou koncentrací aktivních složek. TPR měření prokázala, že vanad promotuje a stabilizuje HDS aktivitu v důsledku zvýšení poměru Mo5+/Mo4+ v katalyzátorech. (cs)
