biostudies-literatureUnknown16(1)Fakhri HAs global fuel standards tighten, stripping sulfur and nitrogen compounds from diesel has emerged as a pivotal hurdle for both environmental protection and industrial innovation. This study explores an innovative route to synthesize metal-organic frameworks (MOFs) infused with Keggin-type polyoxometalates (Mo₆W₆), crafting next-generation nanocomposites tailored for catalytic oxidative desulfurization (ODS) and denitrogenation (ODN). Zirconium- and copper-based MOFs (NUiO-66 and HKUST) were effectively functionalized with Mo₆W₆, a modification verified through FTIR and XRD characterization. Their catalytic performance in eliminating dibenzothiophene (DBT) and quinoline (Qu) from model diesel was assessed under gentle reaction conditions, employing tert-butyl hydroperoxide (TBHP) as the oxiScientific reports4263https://www.ebi.ac.uk/biostudies/studies/S-EPMC12859005biostudies-literatureDevelopment and optimization of polyoxometalate-modified metal-organic frameworks for efficient removal of sulfur and nitrogen compounds from diesel fuel under visible light.PMC12859005Farzadkia MFakhri HMoteallemi AFirooz MHEsrafili AYeganeh MPasalari HfalseDevelopment and optimization of polyoxometalate-modified metal-organic frameworks for efficient removal of sulfur and nitrogen compounds from diesel fuel under visible light.As global fuel standards tighten, stripping sulfur and nitrogen compounds from diesel has emerged as a pivotal hurdle for both environmental protection and industrial innovation.
