NOVELTY - A graphene and porous ferric oxide composite material preparation method involves dissolving a mixture containing iron inorganic salt mixed solution to obtain a mixed solution. The mixed solution in the reaction kettle is reacted with the graphene oxide solution and naturally cooled. The obtained reaction product is cleaned and dried to obtain a graphite and porous ferric oxide precursor. The precursor is calcined to obtain the composite material. USE - Method for preparing a graphene and porous ferric oxide composite material that is utilized in battery, super-capacitance material and automobile. ADVANTAGE - The method enables preparing the graphene and porous ferric oxide composite material in a simple, economical and eco-friendly manner with high surface area and conductivity.
