▎ 摘　　要

NOVELTY - Preparation of graphene alkyne involves (S1) mixing the calcium carbide with the raw materials at a mass ratio of 3-17:1, and then ball-milling the mixture for 1-12 hours under solvent-free conditions to obtain the reaction product, (S2) washing the reaction product obtained in step (S1) with dilute acid, then with deionized water, and finally with alcohol to obtain a washed product, and (S3) obtaining the graphene acetylene material is obtained after drying the washed product obtained in step (S2). USE - Preparation of graphene alkyne used in water treatment, energy storage, semiconductor and catalytic material (all claimed). ADVANTAGE - The synthesized graphene alkyne has various types, adjustable structures, and can combine the excellent properties of graphene and alkyne carbon materials, and has good application prospects in the fields of environment, energy, catalysis and other fields.
