Embodiment 1
[0029] A kind of method utilizing water hyacinth to prepare porous carbon material, comprises the following steps:
[0030] (1) Pretreatment of water hyacinth: take the stem of water hyacinth, wash it, and air-dry it naturally for 5-6 days, then dry it in an oven at 105°C for 24 hours, then crush the dried stem of water hyacinth with a pulverizer, and dry it for 40 Mesh sieve;
[0031] (2) Hydrothermal treatment: Weigh 6.0 g of water hyacinth powder in step (1), add 60 mL of deionized water into a hydrothermal reaction kettle, and mix well; then place the reaction kettle at a temperature of 200° C. After the reaction, filter and dry to obtain lignite-like biomass hydrothermal carbon;
[0032] (3) Molten salt activation treatment: take 2.0g of hydrothermal carbon obtained in step (2), add 8.0gNa 2 CO 3 -K 2 CO 3 Mix the salt, put it in a corundum porcelain boat after mixing evenly, put it in a tube furnace, and put it in the N 2 Under the protection of gas, calcined at 85...
