NOVELTY - Preparation of self-assembly carbon three-dimensional graphene involves using pulping liquid including wood pulp black liquor and herb black liquor. The preparation process involves stirring separation sediment, spray drying in vacuum, mechanically agitating, crushing by ultrasonic waves, freezing in liquid nitrogen, curing, oven-drying, and carrying out deoxy-temperature hydrogen reduction and high-temperature carbonization process. USE - Preparation of self-assembly carbon three-dimensional graphene (claimed). ADVANTAGE - The method efficiently provides self-assembly carbon three-dimensional graphene having stable structure.
