Embodiment 1
[0037] 1) Preparation of carrier mesoporous silica
[0038] Take 45mL of hexadecane bromide (0.148 mol) and 30 mL of acetone into a three-necked flask, stir evenly with a magnetic force, place in a constant temperature water bath at 80°C, take 11mL of tetramethylethylenediamine (0.074 mol) in a constant pressure dropping funnel , drop by drop, heated to reflux for 48h. Cooled to room temperature to obtain a white powdery solid, washed 3 times with an appropriate amount of acetone, filtered and dried to obtain template C 16 -2-C 16 51.2 g.
[0039] The reaction equation is as follows:
[0040]
[0041] Template C was prepared by 8.4 g (0.012 mol) 16- 2-C 16 Dissolve in 150 mL of water, heat to 45°C, and stir evenly until it is completely dissolved, add 6.2 mL of tetraethyl orthosilicate (0.028 mol) to the obtained colloidal solution, add 0.1M NaOH solution dropwise to it to adjust the pH After fully stirring and mixing, the solution was placed in a high-temperature reac...
