Catalytic-oxidative/adsorptive denitrogenation of model hydrocarbon fuels under ultrasonic field using magnetic reduced graphene oxide-based phosphomolybdic acid (PMo-Fe3O4/rGO)

Carbon-Based Materials for Oxidative Desulfurization and Denitrogenation of Fuels: A Review

“…Compared to the silent reaction (no ultrasound), an increase in 50 and 58% removals for PYR and IND, respectively, were observed. This high conversion was maintained for up to 5 cycles [167]. The authors did not highlight the role of the carbon structure.…”

“…Ammar, Kareem, and Mohammed (2020) studied exclusively the ultrasound-assisted catalytic oxidative-adsorptive denitrogenation (COADN) of pyrrole (PYR) and indole (IND) (dissolved in n-nonane, [PYR] 0 and [IND] 0 of 200 ppm) [167] using a PMo-Fe 2 O 3 /rGO as the catalyst. Upon increasing sonication power and time, oxidation of N compounds increased.…”

Sonocatalytic oxidative desulfurization of diesel oil using a novel BiVO4/FeMn LDH nanocomposite

“…28,[30][31][32][33][34][35] There are many materials used in UAODS, such as phosphotungstic acid/activated carbon 36 and reduced graphene oxidebased phosphomolybdic acid. 37 Desai et al used an ionic liquid as an efficient phase transfer catalyst for UAODS. 34 Bismuth vanadate (BiVO 4 ) has been regarded as a promising material owing to its low cost, low toxicity, and high stability.…”

Defective silicotungstic acid-loaded magnetic floral N-doped carbon microspheres for ultra-fast oxidative desulfurization of high sulfur liquid fuels

“…30,31 POMs were immobilized on porous materials to overcome these problems. These materials include zeolite molecular sieves, 32 mesoporous silica, 33 carbon nanotubes, 34 carbon material, 35 graphene oxide, 36 and metal–organic frameworks (MOFs) 37 to form heterogeneous catalysts. Owing to their superior heat, acid, and alkali tolerance, cost economy, ease of supply, and favorable electronic structure, carbon materials have garnered a lot of attention as heterogeneous catalysts.…”
