Preparation and Catalytic Performance of Co-Mo/V₂O₅ Composite Catalyst for Selective Oxidation of Cyclohexane

Abstract:

A new type composite catalyst Co-Mo/V2O5 was prepared by immersion method and characterized by XRD, BET and FT-IR. The effects of Mo mass fraction, immersion time and calcination temperature on catalyst activity for oxidation of cyclohexane were investigated. Co-Mo/V2O5 subjected to immersion with 20% ammonium molybdate solution at room temperature for 1 h and calcination at 600°C exhibited the best performance. Using 0.5 ml of cyclohexane, 3 ml of hydrogen peroxide and 30 mg of catalyst at a reaction temperature of 65°C for 3 h, the cyclohexane conversion was 32.3% and the total selectivity to cyclohexanol and cyclohexanone was 100%.
