  • Catalysts with different V loading and different oxidation degrees were prepared on a zirconia-alumina mixed oxide.

  • The catalytic activity of VOx catalysts was tested in oxidative desulfurization process (ODS).

  • It was used tert-butyl hydroperoxide (TBHP) and hydrogen peroxide as oxidant agents.

  • Reduced vanadium species presented greater reactivity with TBHP, while oxidized vanadium with H2O2.
