[0025] see figure 1 , figure 1 It is a flowchart of a preferred embodiment of a method for preparing a nanostructured graphite carbon material of the present invention, as shown in the figure, including steps:
[0026] S10. After mixing and soaking the plant material and filler for a predetermined time according to a predetermined mass ratio, rolling and extruding are performed to obtain a rolled material;
[0027] S20. Under an inert atmosphere, heating the rolled material to 180-2100° C. and keeping it warm for 0.5-24 hours to obtain a carbonized material;
[0028] S30. Under centrifugation or vacuum conditions, immerse the carbonized material in a strong alkali solution, then heat the carbonized material to 400-1200° C. under an inert atmosphere, and keep it warm for 0.5-24 hours to obtain an activated material;
[0029] S40. Centrifugally clean the activated material, then soak it in a solution containing metal ions, dry it and heat it to 400-1200° C. under an inert atmo...
Embodiment 1
[0047] 1. Rolling: After cleaning and removing impurities, 100g of bagasse is mixed with 40g of liquid water-based acrylic resin and impregnated for 2 hours, and then rolled with a gear-type rolling mill. The rolled material is in the form of scattered materials;
[0048] 2. Carbonization: Put the rolling material into a heating tank, fill it with argon to discharge the air, heat it to 625°C, keep it warm for 6 hours, and after cooling down naturally, complete the carbonization step to obtain carbonized material;
[0049] 3. Activation: Put the carbonized material in the previous step into a vacuum tank, raise the temperature of the carbonized material to 70°C, vacuumize, inject a sodium hydroxide solution with a mass percentage concentration of 70% to soak, and then put the carbonized material into the heating tank after drying , fill up with argon to remove the air, raise the temperature to 780°C, keep it warm for 2 hours, and obtain the activated material after natural cooli...
Embodiment 2
[0052] 1. Rolling: After cleaning and removing 100g of straw stalk slag, mixed with 100g of liquid water-based melamine-formaldehyde resin and end-capped acid catalyst and impregnated for 4 hours, rolling is carried out with a gear and smooth roll rolling mill, and the rolling material produced by rolling is The form is a flat sheet material;
[0053] 2. Carbonization: put the rolling material into a heating tank, fill it up with nitrogen gas to discharge the air, heat it to 600°C, keep it warm for 4 hours, and complete the carbonization step after natural cooling to obtain carbonized material;
[0054] 3. Activation: Put the carbonized material in the previous step into a vacuum tank, raise the temperature of the carbonized material to 70°C, vacuumize, inject a potassium hydroxide solution with a mass percentage concentration of 60% for soaking, and put the carbonized material into the heating tank after drying , fill up with argon to remove the air, raise the temperature to ...
