Abstract
The low efficiency of H2 usage in the oxidation of organics with O2–H2 gas mixture is still a challenging problem. Here, a significant improvement of cyclohexane oxidation has been achieved by introduction of some ionic liquids into Pt/C–H3PMo12O40–CH3CN catalytic system. Even small amounts of BMImBr, Bu4NBr or Bu4NHSO4 inhibited H2O formation, enhanced efficiency of H2 consumption from 2 to 18–25%, and provided extraordinary high selectivity (92–98%) for the conversion of cyclohexane to cyclohexanol. The positive effect of the ionic liquids was explained by stabilization of an active peroxide species and inhibition of secondary oxidation of cyclohexanol.
