A green Hybrid Of (bmim)۵[W۱۲CoO۴۰].۳H۲O catalyzed desulfurization using H۲O۲ asOxidant

The hybrid substituted Keggin-type polyoxometalate (POM), (bmim)۵[W۱۲CoO۴۰].۳H۲O (BWCo)evaluated as catalyst for the selective oxidation of DBT by hydrogen peroxide as a green oxidant. DBT wereoxidized to the corresponding sulfone and sulfoxide with excellent conversion. Our results showed that thiscatalyst could be reused for at least three times without any significant loss of initial catalytic activity.
