NOVELTY - A graphene coated zinc ferrite preparing method involves dispersing oxidized graphene nanolayer in ethylene glycol, stirring to disperse uniformly. Ferric trichloride, zinc chloride and urea are added to the suspension, ferric trichloride and zinc chloride amount-of-substance. The mixed solution is added into the reaction kettle to form a metal alkoxide particles, and the particles attached to the graphene oxide nano-layer on the surface, to obtain graphene coated self-assembly, and is allowed for centrifuging, washing and drying to obtain zinc ferrite. USE - Method for preparing graphene coated zinc ferrite. ADVANTAGE - The method enables preparing ferrite in simple, easy and cost effective manner. DETAILED DESCRIPTION - A graphene coated zinc ferrite preparing method involves dispersing oxidized graphene nanolayer in 0.01-5.0 mg/ml ethylene glycol, ultrasound for 30-60 minutes, stirring to disperse uniformly. 0.05-0.5 ml/l Ferric trichloride, zinc chloride and urea are added to the suspension, ferric trichloride and zinc chloride amount-of-substance concentration ratio is 2: 1, stirred for 0.5-5.0 hours to disperse uniformly. The mixed solution is added into the reaction kettle, at 60-160 degrees C for 0.5-5.0 hours, to form a metal alkoxide particles, and the particles attached to the graphene oxide nano-layer on the surface, and kept at 180-250 degrees C for 4-48 hours, to obtain graphene coated self-assembly, and is allowed for centrifuging, washing and drying to obtain the graphene coated with nanoparticles of a zinc ferrite.
