description | The invention discloses a preparation method of gamma-graphdiyne powder. The preparation method comprises the following steps: using hexabromobenzene and calcium carbide powder in a molar ratio of 1:(3-18) as reaction precursors, mixing the reaction precursors with absolute ethyl alcohol to prepare slurry; sealing the opening of a slurry container, and stirring for 23-28 hours at a constant temperature of 75-85 DEG C so that the precursor in the slurry is subjected to a coupling reaction; and after the reaction is finished, removing impurities through annealing and washing to obtain high-purity fluffy gamma-graphdiyne powder. According to the preparation method of the gamma-graphdiyne powder, the experimental process is more transparent and controllable, the requirement for preparation instruments is low, energy consumption in preparation is low, most of preparation processes can be conducted in the normal-temperature and normal-pressure air atmosphere, the preparation toxic and sideeffects are small, the ope |
