▎ 摘  要

NOVELTY - Preparing high-quality graphene from plant membrane comprises (i) selecting plant film layer-containing plant tissue, cleaning, adding ethanol and ultrapure water to obtain a mixed solution, adjusting pH of the mixed solution to 2-4, soaking the cleaned plant tissue in mixed solution for activating, (ii) taking out, immersing in a glucose solution, hexagonal-mesh processing, (iii) separating, carrying out centrifugal separation, washing and drying, (iv) heating under the protection of nitrogen, calcining and drying, (v) cooling the product to room temperature. USE - The method is useful for preparing high-quality graphene from plant membrane (claimed). ADVANTAGE - The method is non toxic, economical, environmentally-friendly and is suitable fro industrial popularization. DETAILED DESCRIPTION - Preparing high-quality graphene from plant membrane comprises (i) selecting plant film layer-containing plant tissue, cleaning, adding ethanol and ultrapure water to obtain a mixed solution, adjusting pH of the mixed solution to 2-4, soaking the cleaned plant tissue in mixed solution for activating, (ii) taking out, immersing in a glucose solution, hexagonal-mesh processing, (iii) separating the processed plant tissue, carrying out centrifugal separation, washing and drying, (iv) heating under the protection of nitrogen, calcining and drying plant tissue, (v) cooling the product to room temperature to obtain the high-quality graphene.
