- •
Highly surface area NiMoS catalysts supported on SiO2, SiO2 -TiO2, SiO2-ZrO2.
- •
Zr or Ti atoms were plenty incorporated into the silica framework.
- •
HRTEM and Raman analyses evidenced the formation of well dispersed MoS2 slabs.
- •
Edge-bonded MoS2 slabs were more formed on catalysts one-pot prepared.
- •
NiMoS HDS catalysts prepared by the one-pot methodology were the most active.
