Item Restricted Polyoxometalate catalysis for oxidative desulfurization(Saudi Digital Library) RANA OMAR HASSAN YAHYA; In this study, new efficient catalysts have been developed for the oxidation of benzothiophenes commonly found in diesel fuel, such as benzothiophene, dibenzothiophene and 4,6-dimethyldibenzothiophene, to the corresponding sulfones with hydrogen peroxide in two-phase system including immiscible aqueous and organic phases. These catalysts are based on polyoxometalates comprising Keggin type heterop0 0
