Embodiment 1

[0017] A hydrothermal preparation method of bamboo fiber nano-carbon particles comprises the following steps: sieving bamboo powder, pretreatment, ball milling, dispersion, hydrothermal reaction, centrifugation, washing and drying. Specific steps are as follows:

[0018] (1) Bamboo powder is passed through a sieve with a sieve hole diameter of 0.15mm, and is set aside;

[0019] (2) Treat the sieved bamboo powder with a mixed solution of hydrogen peroxide and urea to remove impurities, wash with water, and dry to obtain bamboo powder crude fiber;

[0020] (3) Take 30g of bamboo powder crude fiber and place it in a ball mill, add absolute ethanol as a dispersion medium, and grind for 3 hours to obtain bamboo fiber powder;

[0021] (4) Disperse the bamboo fiber powder in water, stir at room temperature for 3 hours to get a paste; 25ml of water is needed for every 1g of bamboo fiber powder;

[0022] (5) Transfer the paste to a high-pressure reactor at a constant temperature of 2...
