▎ 摘 要
NOVELTY - Sulfonated graphene material is prepared by reacting and reducing graphene oxide and aryl p-aminobenzenesulfonic acid diazonium salt as raw materials. USE - Preparation of sulfonated graphene material (claimed). ADVANTAGE - The method enables preparation of sulfonated graphene material with high yield by safe, simple and environmentally-friendly method at low-temperature and mild reaction conditions, with low production equipment requirement.
