Embodiment 1-5
[0027] The bamboo processing waste is crushed to a length of 1-15mm, dried at 100°C for 2 hours, and irradiated by a radiation source 60 Co, radiation dose rate 2.6×10 3 Gy / h, the irradiation dose is 10000Gy, and then impregnated with 30% potassium hydroxide solution for 24h, the mass ratio of alkali to carbon is 1:1, 2:1, 3:1, 4:1, 5:1 , put it into a microwave oven, microwave at a power of 700W for 12min, take it out and wash it with water, soak it in 10% (wt%) hydrochloric acid for 4h, then wash it to neutral, dry it in an oven at 100°C, and then crush it to -400 mesh to obtain activated carbon . The activated carbon of Examples 1-5 is used as a material to prepare a supercapacitor, using 30% (wt%) KOH aqueous solution as the electrolyte, the charge and discharge voltage range is 0.05-1.0V, and the charge and discharge current is 300mA / g. The corresponding data are shown in the table 1.
Embodiment 6-9
[0029] Crumble the bamboo processing waste to a length of 1-15mm, dry at 110°C for 1.5h, and use a radiation source 60 Co, radiation dose rate 2.6×10 3 Gy / h, the irradiation dose is 30000Gy, and then impregnated with 30% potassium hydroxide solution for 48h, the mass ratio of alkali to carbon is 3:1, put it into a microwave oven, under the power of 200W, 400W, 700W, 900W respectively Microwave for 12 minutes, and the steps after taking it out are the same as in Example 1-5. The corresponding data are shown in Table 2.
Embodiment 10-13
[0031] Crumble the bamboo processing waste to a length of 1-15mm, dry at 120°C for 1h, and use a radiation source 60 Co, radiation dose rate 2.6×10 3 Gy / h, the irradiation dose is 50000Gy, and then impregnated with 30% potassium hydroxide solution for 10h, the mass ratio of alkali to carbon is 3:1, microwave 10min, 12min, 15min, 20min under the power of 700W respectively, and take out the following steps With embodiment 1-5. The corresponding data are shown in Table 3.
