NOVELTY - Preparation of reduced graphene oxide/ferrocene composite material involves ultrasonically dispersing a reduced graphene oxide in an ethanol-water mixed solvent to form an uniform suspension, adding ferrocene ethanol solution to the suspension, stirring for 2-3 hours, leaving still for 30-40 minutes, separating, washing with water to remove ethanol, and drying. USE - Preparation of reduced graphene oxide/ferrocene composite material. ADVANTAGE - The composite material has regular morphology and more pore structure, can be easily introduced into various groups (molecules, drugs, or metal oxide) in the void, and has excellent electrical properties due to the use of ferrocene.
