Deep aerobic oxidative desulfurization of model fuel by Anderson-type polyoxometalate catalysts

Anderson-type polyoxometalate (POM) catalysts were synthesized and applied for deep oxidative desulfurization of model fuel containing dibenzothiophene. O2 contained in air was used as oxidant under mild conditions. The influence of the nature of central heteroatom and that of the quaternary ammoniu...
