Example Embodiment
[0047] Example 1: Using chemical activation method, Yangxu is carbonized in a tube furnace under Ar atmosphere, and then ZnCl is used 2 After the solution is immersed for 10-20 hours, it is placed in the center of the tube furnace, heated to 500-2000 ℃ in Ar atmosphere, activated for 0.5-10 h and then cooled to room temperature in Ar atmosphere, finally washed and dried to obtain microporous carbon micron tube. Using physical activation method, Yangxu is carbonized in a tube furnace under Ar atmosphere for a period of time, then the temperature is increased to 800~2000 ℃, and then CO is introduced. 2 The gas is activated for 0.5-10 h, and finally cooled to room temperature under Ar atmosphere to obtain the product. The chemical and physical activation method is adopted, and the product obtained by the chemical activation method is placed in the middle of the tube furnace, and then CO is introduced 2 The gas is treated for 10-60 minutes and cooled to room temperature to obtain ...

[0048] Example 2: Using chemical activation method, Yangxu was carbonized in a tube furnace under Ar atmosphere, and then immersed in KOH solution for 10-20 hours, then placed in the center of the tube furnace, and heated to 500-2000 ℃ in Ar atmosphere. After activation for 0.5-10 h, it was naturally cooled to room temperature under Ar atmosphere, and finally washed and dried to obtain porous carbon microtubes. Using physical activation method, Yangxu is carbonized in a tube furnace under Ar atmosphere for a period of time, then the temperature is increased to 800~2000 ℃, and then CO is introduced. 2 The gas is activated for 0.5-10 h, and finally cooled to room temperature under Ar atmosphere to obtain the product. The chemical and physical activation method is adopted, and the product obtained by the chemical activation method is placed in the middle of the tube furnace, and then CO is introduced 2 The gas is treated for 10-60 minutes and cooled to room temperature to obtain ...
