Highly active hydrodesulfurization (HDS) catalysts have been prepared successfully through a molecular approach using well-defined Strandberg PMoNi polyoxometalates (POMs) as superior precursors. The hand-picked POMs significantly facilitated not only the formation of highly dispersed NiMo species but also the formation of abundant and accessible NiMoS active sites at lower sulfidation temperatures,...
NiMo catalysts were prepared using Waugh-type NiMo heteropolycompounds as active phase precursors and evaluated in hydrodesulfurization (HDS) of dibenzothiophene (DBT). These catalysts were compared with corresponding reference catalysts prepared from the conventional precursors (ammonium heptamolybdate and nickel nitrate). Prepared catalysts were characterized by N2 physisorption, XRD, FT-IR, H2-TPR,...
