Among these catalysts, Sn/SBA-15(50) exhibited the highest catalytic activity for Baeyer-Villiger oxidation of cyclohexanone to ε-crolactone using hydrogen peroxide (H2O2) as the green oxidant. The best methodology was to carry out the reaction in 1,4-dioxane under 10wt% Sn/SBA-15 catalyst of 0.1mol cyclohexanone at 70°C for 4h, and a molar ratio cyclohexanone: oxidant of 1:3. Furthermore, this heterogeneous mesoporous Sn/SBA-15 catalyst was reusable without any appreciable loss in activity and selectivity after three cycles.
