A series of Mg-based catalysts were prepared by the coprecipitation method and were characterized by XRD, BET, and TG-DTA. As compared with other composite catalysts, including MgO/Al2O3, MgO/La2O3, MgO/TiO2, MgO/ZnO, and MgO/ZrO2, MgO/SnO2 showed the most efficient catalytic performance in the Baeyer-Villiger oxidation of cyclohexanone to ε-caprolactone with aqueous hydrogen peroxide as oxidant. Under optimal reaction conditions, the as-prepared MgO/SnO2 catalyst after calcined at 600℃ with the Mg/Sn molar ratio of 7:3 presents an excellent performance with the cyclohexanone conversion of 90.5% and the caprolactone selectivity of 100%.
