Precise tuning the CoMoO /Al2O3 and CoMoS /Al2O3 interfacial structures for efficient hydrodesulfurization of dibenzothiophene

Atomic-Layer-Deposition Derived Pt subnano Clusters on the (110) Facet of Hexagonal Al2O3 Plates: Efficient for Formic Acid Decomposition and Water Gas Shift

“…It was found out that the Pt/(110) interface significantly outperforms the other interfaces for WGS (Figure S7). Our previous studies also demonstrated that the sulfide/Al 2 O 3 (110) interface is superior to the sulfide/Al 2 O 3 (111) & (100) interfaces for the hydrodesulfurization of dibenzothiophene and water gas shift . On the (110) facet of γ-Al 2 O 3 , more active MoS 2 and Co 9 S 8 /Co–Mo–S species are favorably formed while less active CoMoO x S 2 and SO x 2– species are constrainedly produced.…”

“…Our previous study indicated that, in the case of hexagonal Al 2 O 3 , the areal coverage of the (110) facet reaches approximately 90%, whereas that of (111)/(100) facets corresponds to only about 10%. In other words, the M/(110) interface is significantly dominant over the hexagonal Al 2 O 3 supported Pt catalyst.…”

“…Clearly, the current study demonstrated that the unique synergism involved between the ultrafine Pt entity and the specific (110) facet of Al 2 O 3 can result in outstanding performance for WGS, confirming the ALD-based approach to achieving the highperformance system for low-temperature WGS. 80 Our previous study 89 indicated that, in the case of hexagonal Al 2 O 3 , the areal coverage of the (110) facet reaches approximately 90%, whereas that of (111)/(100) facets corresponds to only about 10%. In other words, the M/ (110) interface is significantly dominant over the hexagonal Al 2 O 3 supported Pt catalyst.…”

High-Density Jet-Fuel Hydrocarbons from Biomass-derived Cyclic Ketones via Vapor Phase Hydrodeoxygenation over Ru-Ni2P/Al (10)-KIT-6

“…The possible outcome of di-cyclohexyl methane (DCM), − bi-cyclohexane (BCH), and decalin (DC) can be synthesized from different feedstocks such as 2-benzyl phenol, diphenyl ketone, , di-phenyl methane, 2-benzyl 4-ethyl phenol or 3-benzyl 4-ethyl phenol, benzofuran, benzyl phenyl ether, phenol with dibenzyl ether, and phenol with benzyl acetate for DCM; dibenzofuran, , dibenzothiophene, carbazole, cyclohexanone, biphenyl, 5,5′-biphenol, and phenol for BCH; − and α-tetralone, tetralin, , naphthalene, − α-naphthol, , and cyclopentanone for DC. The aforementioned feedstocks have been converted to jet-fuel range hydrocarbons through vapor phase and liquid phase catalytic reactions with various types of metal-containing catalysts.…”

“…Dicyclohexyl methane was obtained from the above-mentioned feedstocks using Pd/C-HZSM-5, Ru@SILP (Ph 3 -p-NTf 2 ), Pd loaded (C, Al 2 O 3 , BETA, ZSM-5, MCM-41), Pt (111), Ru/Al 2 O 3 -zeolite (HY), SAA-57/Ru-CSA, and MMT-KSF/K-10 catalysts. − Hydrodeoxygenation of 2-benzyl-4-ethyl phenol and alkylation of phenol with dibenzyl ether have been reported using an HZSM-5 + Pd/C catalyst system for DCM conversion . Mesoporous silica COK-12, Al 2 O 3 -ZrO 2 /SiO 2 , CoMoOx/Al 2 O 3 and CoMoSx/Al 2 O 3 , Fe-Co/Ni 2 P, alumina supported CoMo and NiMo catalysts, Ru nanoparticles on SiO 2 , Pt/C, Ru/HZSM-5 and Hβ/Pd-C catalysts have also been reported to convert the above starting materials to bi-cyclohexane. − Cecilia and co-workers reported on the role of phosphorous in the removal of oxygen from dibenzofuran using Ni 2 P catalysts . Nagai et al reported Mo-supported Al 2 O 3 catalysts employed for carbazole hydrodenitrogenation .…”
