“…The above‐mentioned changes in HRTEM results of sulfide NiMo/LaAlO x ‐ m samples should be related to the changes in MSI in NiMo/LaAlO x ‐ m oxide catalysts. It has been acknowledged that moderate MSI is favorable for the formation of “Type II” NiMoS active phase, which is thought to be more reactive in 4,6‐DMDBT HDS reaction than that of “Type I” NiMoS phase 46 . In addition, the proper length of Ni promoted MoS 2 slab will promote the HDS activity of 4,6‐DMDBT over sulfide catalyst, because the activity of the DDS pathway of HDS catalysts is strongly related to Mo atoms at corner positions, and the HYD pathway is positively associated with the Mo atoms at edge sites.…”

Herein, a series of mesoporous NiMo/LaAlO x with various La contents were constructed through a solvent evaporation-induced self-assembly protocol, and their catalytic activities were investigated for hydrodesulfurization (HDS) of 4,6-DMDBT.It has been confirmed that the incorporation of La influences the electronic structure and morphology of NiMoS active phase. The lower amount of La (x ≤ 1.0 wt.%) could facilitate the formation of "Type II" NiMoS phase by weakening the interaction of Mo-O-Al leakage and promoting the sulfidation of both Mo and Ni species as well as increasing the ratio of "Type II" NiMoS phase, thereafter boosting the HDS performances. Further increasing La incorporation, however, leads to the generation of inactive NiS x phase and decrease of NiMoS active phase proportion, the HDS activities of corresponding catalysts were suppressed. NiMo/LaAlO x -1.0 exhibits the highest activity for 4,6-DMDBT HDS because of its moderate metal-support interaction, optimal morphology and the largest proportion of "Type II" NiMoS active phase.
