[0026] A preparation method for ammoniated aromatic graphene, comprising the following steps:
[0027] a) dissolving the higher alkyne polymer of acetylene tail gas in an alcohol solvent to obtain the first mixed solution;
[0028] b) dissolving nickel acetate in aqueous ammonia into the first mixed solution obtained in step a) through a metering jet pump, and reacting by heating to obtain a second mixed solution;
[0029] c) cooling the second mixed solution obtained in step b) to room temperature, then adding hydrazine hydrate to react to obtain a mixture of methylpyrazole and aromatic graphene microcrystalline nickel; The mixture of graphene microcrystalline nickel is cooled to room temperature, diluted with deionized water, then filtered to obtain metallic nickel and carbon solids, sent to an alcohol eluting tower, and the metallic nickel is eluted and extracted, and the eluent is returned to the reaction In the material, a mixture of methylpyrazole and aromatic graphene ...
