Precise tuning the CoMoOx/Al2O3 and CoMoSx/Al2O3 interfacial structures for efficient hydrodesulfurization of dibenzothiophene

● Morphologically uniform γ-Al2O3 hexagonal plates, stacked hexagonal plates, and rods controllably prepared. ●The specific (110), (100)/(111), and poly-crystalline facets of γ-Al2O3 supports available for catalyst design. ●Precise tuning the oxidic and sulphurated interfacial structures with distinct γ-Al2O3 facets and Co/Mo loadings. ●Highest content of MoS2/Co9S8/CoMoS and highest activity of DHS of DBT on the (110) facet-based catalyst. ●Enhanced MoS2-CoMoS/MoS2-Co9S8 conjunction and synergism more efficient for the target reaction.
