Oxidation of cyclohexane with hydrogen peroxide over β-zeolites with various Si/Al ratios

► β-Zeolite indicated high activity for BV oxidation of cyclohexanone with H2O2. ► The Brønsted acidity of β-zeolites plays an important role in activation of H2O2. ► Cyclohexanone was activated on the silanol groups on β-zeolite.
