Embodiment Construction
[0011] The technical characteristics and advantages of the present invention can be seen through the embodiments and application examples given below.
[0012] 1. MnO X / ZrO 2 Structural Properties of Catalysts
[0013] The preparation of the catalyst adopts the equal-volume impregnation method. A certain amount of manganese acetate is added to deionized water, and then a certain amount of mesoporous zirconia is added to the solution to make MnO X / ZrO 2 Medium Mn (as MnO 2 Calculation) percentage is 1-15wt%, impregnated at room temperature for 0.5-6 hours, the obtained system is dried in an oven at 100-140°C for 1-6 hours, then washed with deionized water, and then dried at 100-140°C for 1 hour -6 hours, and finally calcined the obtained powder at 300-500°C for 2-6 hours to obtain MnO X / ZrO 2 sample. In order to compare the superiority of the catalyst prepared by the present invention, the same preparation method was adopted with mesoporous zirconia and commercially a...
