A new type composite catalyst of V2O5 comprising Co-Mo/V2O5 was prepared by immersion method and characterized by XRD. The characteristic peaks of CoMoO4(2θ=28.51°) and CoMoO3(2θ=18.06 °)are both observed in the XRD patterns of Co-Mo/V2O5(5%, 20%) catalysts. The oxidation of cyclohexane with hydrogen peroxide was used as a probe reaction to investigate the effects of some conditions, such the sort and volume of solvent, catalyst amount, oxidant amount, reaction temperature and time, on reaction. Using 0.5 ml of cyclohexane, 10 ml of acetonitrile, 3 ml of hydrogen peroxide and 0.03 g of catalyst at a reaction temperature of 55°C for 3 h, the cyclohexane conversion was 32.3% and the total selectivity to cyclohexanol and cyclohexanone was 100%.
