TL;DR: A novel nanocomposite based on mono CdII‐substituted silicotungstate, cobalt ferrite and polyaniline was synthesized and characterized. The nanocomposite was employed as a heterogeneous catalyst in the extractive coupled oxidative desulfurization (ECOD) of real fuels. The catalyst exhibited high activity and reusability in the ECOD process.

Poly(ionic liquid)–polyoxometalate/graphene oxide composites as catalysts for deep desulfurization
01 Jan 2022
TL;DR: In this article , a series of supported catalysts were synthesized by loading polyoxometalate salts on the graphene oxide surface, and the maximum desulfurization rates of T, BT and DBT can reach 98.32, 99.98 and 99.28%, respectively.

Synthesis and characterization of (TBAPW11O39) hybrid Keggin type catalyst
TL;DR: In this paper , a hybrid organic-inorganic polyoxotungstate [TBAPW11O39] was synthesized by the method which quaternary ammonium is introduced to a Keggin structure of polyoxometalate by metathetical organic cation exchange by adding tetrabutylammonium bromide (TBABr) to the solution of sodium salts in a heteropolyanion.

Oxidative processes of desulfurization of liquid fuels
TL;DR: In this paper, the developments in selective removal of organosulfur compounds present in liquid fuels via oxidative desulfurization, including both chemical oxidation and biodesulfurisation, are reviewed.
Biodesulfurization of refractory organic sulfur compounds in fossil fuels
TL;DR: More work is needed in areas such as increasing specific desulfurization activity, hydrocarbon phase tolerance, sulfur removal at higher temperature, and isolating new strains for Desulfurizing a broader range of sulfur compounds.

Liquid phase adsorption by microporous coordination polymers: removal of organosulfur compounds.
TL;DR: It was determined that the size/shape of the pores in the MCP, rather than the surface area or pore volume, is the most important factor controlling adsorption capacity.
