Embodiment 1
[0025] Weigh 1.25 g of sucrose and place it in a beaker, then use a graduated cylinder to measure 5 mL of deionized water and add it to the above beaker, stir until completely dissolved, then add 0.14 g of concentrated sulfuric acid dropwise as a dehydrating agent and stir evenly. Weighed 1 g of SBA-15 and slowly added it into the above solution and continued to stir until it became a white viscous paste, followed by ultrasonic treatment for 10 min to improve its dispersibility. It was dried in an oven at 100 °C for 6 hours, then heated to 160 °C and dried for 6 hours to obtain a composite of ordered mesoporous carbon and SBA-15.
[0026]Weigh 1 g of the above composite solid and grind it into a powder, mix it with 5 g of ammonium dihydrogen phosphate and dissolve it in deionized water, then place it in a water bath at 60 °C to evaporate the solvent water, and after drying, grind the obtained powder into a powder in Calcined at 800 °C for 5 hours in a tube furnace under an arg...
Embodiment 2
[0030] Weigh 2.25 g of glucose and place it in a beaker, then use a graduated cylinder to measure 5 mL of deionized water and add it to the above beaker, stir until completely dissolved, then add 0.24 g of concentrated sulfuric acid dropwise as a dehydrating agent and stir evenly. Weighed 1 g of SBA-15 and slowly added it into the above solution and continued to stir until it became a white viscous paste, followed by ultrasonic treatment for 10 min to improve its dispersibility. It was dried in an oven at 100 °C for 6 hours, then heated to 160 °C and dried for 6 hours to obtain a composite of ordered mesoporous carbon and SBA-15.
[0031] Weigh 1 g of the above composite solid and grind it into a powder, mix it with 5 g of ammonium phosphate and dissolve it in deionized water, then place it in a water bath at 80 °C to evaporate the solvent water, and after drying, grind the obtained powder into a powder in a tube Calcined at 800°C for 5 hours under an argon atmosphere in the f...
Embodiment 3
[0035] Weigh 1.25 g of fructose and put it in a beaker, then use a graduated cylinder to measure 5 mL of deionized water and add it to the above beaker, stir until completely dissolved, then add 0.14 g of concentrated sulfuric acid dropwise as a dehydrating agent and stir evenly. Weighed 1 g of SBA-15 and slowly added it into the above solution and continued to stir until it became a white viscous paste, followed by ultrasonic treatment for 10 min to improve its dispersibility. It was dried in an oven at 100 °C for 6 hours, then heated to 160 °C and dried for 6 hours to obtain a composite of ordered mesoporous carbon and SBA-15.
[0036] Weigh 1 g of the above composite solid and grind it into powder, mix it with 7 g of hexachlorotripolyphosphazene and dissolve it in deionized water, then place it in a water bath at 60 °C to evaporate the solvent water, and after drying, grind the obtained product into The powder was calcined at 600 °C for 5 hours under an argon atmosphere in ...
