摘要（英）：

The invention relates to a method for preparing cyclohexanol and cyclohexanone by oxidizing cyclohexane, in particular to a method for preparing a vanadium-doped ZSM-5 molecular sieve and a catalytic property of the molecular sieve on preparation of cyclohexanol and cyclohexanone by oxidizing cyclohexane. A molar ratio of vanadium to silicon in the microporous molecular sieve is 0.02-0.03, oxygen and the like are taken as an oxidant, reaction is performed at the temperature of between 80 and 150DEG C under the pressure of between 0.5 and 2.5MPa for 1 to 10 hours, the conversion rate of the cyclohexane is 14.68 percent, and the sum of the selectivity on the cyclohexanol and the cyclohexanone is 97.3 percent. The method has the characteristic that transition metal V atoms in the V-ZSM-5 molecular sieve prepared by a direct hydrothermal synthesis method can enter the skeleton of the molecular sieve so as to greatly improve the activity and selectivity of oxidation reaction.
