	abstract = {<p>The heterogenization of the highly active monovacant polyoxotungstate ([PW11O39]7 -, abbreviated as PW11) was achieved by preparing the corresponding long chain quaternary ammonium salt (ODA7PW11, ODA = CH3(CH2)17(CH3)3N). The complete cation exchange confers total heterogeneity to the monovacant catalyst while keeping its oxidative catalytic activity. In fact, the heterogeneous catalyst allowed for the complete desulfurization of a multicomponent model diesel (2000 ppm S) after 40 min of reaction, conciliating extraction (using BMIMPF6 solvent) and oxidation (ECODS process using H2O2 oxidant). The heterogeneous catalyst has shown a superior desulfurization performance when compared with the homogeneous quaternary ammonium TBAPW11 catalyst (TBA = (C4H9)4 N). Both hybrid catalysts have been successfully reused in consecutive ECODS cycles. Additionally, the long carbon chain cations provide a protective environment around the polyoxometalate allowing for ODA7PW11 to retain its heterogeneity and structure after the ECODS process.</p>
