NOVELTY - The preparation method of flower-like micro-structured-( gamma )-ferric oxide/reduced graphene oxide composite material involves adding soluble iron salt to graphene oxide-ethylene glycol solution, uniformly stirring, dripping sodium hydroxide aqueous solution, after finishing dripping, stirring for 30 minutes, reacting at 150-180 degrees C for 12-18 hours, washing, and drying. USE - Preparation method of flower-like micro-structured-( gamma )-ferric oxide/reduced graphene oxide composite material. ADVANTAGE - The method enables preparation of flower-like micro-structured-( gamma )-ferric oxide/reduced graphene oxide composite material with large number of void structures, increased specific surface area and reactivity site, and excellent catalytic effect.
