Efficient aerobic oxidative desulfurization over Co–Mo–O bimetallic oxide catalysts

Abstract

Co–Mo–O bimetallic oxides were prepared as efficient catalysts for aerobic oxidative desulfurization with oxygen in air as the oxidant.

Creation of Active Sites in MOF‐808(Zr) by a Facile Route for Oxidative Desulfurization of Model Diesel Oil

“…This means that 4,6‐DMDBT should be easily oxidized when compared with BT and DBT. In fact, some earlier reports displayed the difficulty of oxidation in the order of BT > DBT > 4,6‐DMDBT . However, in this work, the catalytic data show that the conversion of sulfur compounds follows the order of DBT > BT > 4,6‐DMDBT.…”

A current overview of the oxidative desulfurization of fuels utilizing heat and solar light: from materials design to catalysis for clean energy

“…To clarify this, Co-Mo-O nanorods and nanosheets were fabricated by the co-precipitation method prior to calcination (Fig. 6d) in the works of Zhang et al and Dong et al 75,77 As seen in Fig. 6e and f, the thickness of the Co-Mo-O nanosheet was around 2-3 nm, which was thinner than the Co-Mo-O nanorod with a 80-120 nm width.…”

“…In view of the catalyst morphology's impact on ODS activity, a few recent studies have signified that nanorod and nanosheet mixed metallic oxide catalysts are potentially the key to ODS advancement. [75][76][77] However, the decision on whether nanosheet catalysts perform better than nanorod catalysts in ODS is still under debate. To clarify this, Co-Mo-O nanorods and nanosheets were fabricated by the co-precipitation method prior to calcination (Fig.…”

Solvothermal synthesis of Co-substituted phosphomolybdate acid encapsulated in the UiO-66 framework for catalytic application in olefin epoxidation

“…As shown in Fig. 7(B), the XPS profiles of Co 2p for PMo11Co present two main peaks centered at around 795.5 and 780.2 eV, which were ascribed to Co II 2p1/2 and Co II 2p3/2, respectively [43][44][45]53,54]. The Co 2p signals of PMo11Co@UiO-66 exhibited a slightly negative shift (795.1 and 779.8 eV) compared to those of PMo11Co, thus providing further evidence that the chemical environments of the Co substituted POM units change to some extent after being introduced 1800 1600 1400 1200 1000 800 600 into the ZrMOFs due to the presence of host-guest interactions.…”
