Example Embodiment
[0026] Example 1 (Example of the best reaction conditions): Dissolve 2.1840g CTAB in 50ml water, stir for 10min to make it clear, add NaOH (0.3435g) and 10ml water, control the pH of the solution to 9, and obtain a colorless homogeneous solution . Then 14.42g TEOS was slowly added to obtain a milky white turbid liquid. After stirring and reacting at room temperature for 8 hours, the solution was placed in the reactor at 100 0 C reacts for 3 days. Suction filtration, washing with ethanol and water twice to obtain a white solid, the white solid is 550 0 C, fired in the muffle furnace for 6h, 750 0 C burned for 11h to obtain a macroporous molecular sieve (MMCM), 11.6 g, and the yield was 78%. Infrared spectrum data (IR, cm -1 ): 1089, 800, 432. BET: 21.54m 2 g ?1 ; The aperture is 100 nm (see attached figure 1 )

[0028] And 10ml of water, control the pH of the solution to 8, to obtain a colorless homogeneous solution. Then 14.42g TEOS was slowly added to obtain a milky white turbid liquid. After stirring and reacting at room temperature for 8 hours, the solution was placed in the reactor at 100 0 C reacts for 3 days. Suction filtration, washing with ethanol and water twice to obtain a white solid, the white solid 650 0 C, fired in the muffle furnace for 6h, 900 0 C burned for 11h to obtain a macroporous molecular sieve (MMCM), 8.6 g, and the yield was 58%. Infrared spectrum data (IR, cm -1 ): 1089, 800, 432.

[0029] Example 3: Dissolve 2.1840g CTAB in 50ml water, stir for 10min to make it clear, add NaOH (0.3435g) and 10ml water, control the pH of the solution to 10, and obtain a colorless homogeneous solution. Then 14.42g TEOS was slowly added to obtain a milky white turbid liquid. After stirring and reacting at room temperature for 8 hours, the solution was placed in the reactor at 100 0 C reacts for 3 days. Suction filtration, washing with ethanol and water twice to obtain a white solid, the white solid is 550 0 C, burned in the muffle furnace for 6h, 800 0 C burned for 11h to obtain a macroporous molecular sieve (MMCM), 7.8 g, and the yield was 53%. Infrared spectrum data (IR, cm -1 ): 1089, 800, 432.
