▎ 摘  要

NOVELTY - The preparation method of three-dimensional graphene involves dissolving pure ethyl cellulose and sodium hydroxide in ethanol in a molar ratio of 1:1 to obtain a sol, aging sol at room temperature to obtain gel, drying gel to obtain a dry gel, carbonizing the dry gel under argon gas atmosphere in a tube furnace at 700-1000 degrees C, washing the carbonized product with deionized water until the pH of solution is 6.8-7.2, suction-filtering the solution, suction filtering to obtain product, and drying. USE - Preparation of three-dimensional graphene (claimed). ADVANTAGE - The method enables the preparation of three-dimensional graphene by simple process at low cost using readily available raw materials with less energy.
