Embodiment 1
[0037] (1) Break the coconut shell, sieve out the silky shredded coconut, wash and dry it with deionized water, put it into a corundum boat and put it in a tube furnace. -1 The temperature was raised to 400°C for 2 hours at a certain rate, and after the heating was completed, it was naturally cooled to room temperature to obtain pre-carbonized material A1;
[0038] (2) Transfer material A1 to a beaker, add 100ml of 6mol L at 60°C -1 Potassium hydroxide solution, 300r min -1 Stir for 8 hours, then filter with suction, wash with deionized water until the filtrate is neutral, transfer the filter cake to a beaker, and then add 100ml of 1mol L -1 HCI, 300r min -1 Stir for 1 hour, filter with suction, wash with deionized water until the filtrate is neutral, and dry to obtain material B1;
[0039] (3) Dissolve 0.15g of potassium hydroxide and 0.45g of potassium bicarbonate in deionized water to form a 20ml mixed solution. Then take 0.15g of material B1 and put it into the mixed so...
