Embodiment 1
[0037] The composite material of rod-shaped molecular sieve SBA-15 surface coated with carbon layer is prepared, and the preparation steps are as follows:
[0038] Weigh 4g SBA-15 (the specific surface area is 613.56m 2 / g, the average pore diameter is 7.74nm) was put into an oven and dried at 120°C for 12 hours, placed in a 100mL glass flask filled with 40mL of anhydrous toluene under a nitrogen atmosphere, stirred evenly by magnetic force, and added 4.8mL of 3-aminopropyl Trimethoxysilane, stirred and refluxed at 110°C for 12 hours, filtered under reduced pressure and washed with anhydrous toluene, dichloromethane, methanol, water, methanol in sequence, and dried at 80°C to constant weight to obtain the aminated mesoporous support . Put the above-mentioned aminated mesoporous carrier in a 500 mL hydrothermal kettle lined with polytetrafluoroethylene, add 12g of glucose and 200mL of water in sequence, stir evenly, tighten the reaction kettle, and place it in a heating device...
