Embodiment 1
[0032] 1.15g zinc and 3.9g sucrose are mixed ball milled, the ball-to-material ratio is 10:1, the rotating speed is 300rpm, ball milled for 6h, the resulting mixture is sealed in a stainless steel autoclave in a glove box full of inert gas, and then the autoclave is pumped Vacuum to below 0.1MPa; heat the autoclave to 550°C with an electric furnace, react for 8 hours and then cool it down to room temperature naturally to obtain the reaction product. Take the loose part of the upper layer of the reaction product and ball mill it at a speed of 300rpm for 6 hours. First wash with dilute hydrochloric acid with a concentration of 0.1M until no bubbles are generated, then wash with deionized water until the pH is neutral, and dry at 100° C. for 10 h to obtain porous nano-carbon flakes.
[0033] The porous nano-carbon flakes prepared in the present embodiment are tested, and the results are as follows:
