Abstract

The invention discloses a method for preparing a graphene / ferric oxide composite material. The method comprises the following steps: (1) putting a mixed solution of deionized water and ethanol amine into graphene oxide, and performing ultrasonic dispersion; (2) dissolving PEG-10000, ammonium ferrous sulfate and hexamethylenetetramine into the mixed solution; (3) placing the mixed solution in a sealed environment, and keeping the temperature of 180-200 DEG C for 15-20 hours; and (4) washing and drying a reactant, thereby obtaining ferric oxide magnetic nano particles. The ferric oxide nano particles prepared by using the method are uniformly dispersed on a graphene layer, so that agglomeration of graphene is effectively avoided, and the prepared graphene / ferric oxide composite material is excellent in photocatalytic degradation activity under radiation of ultraviolet radiation, is good in stability, has ferromagnetic behaviors, and can be effectively separated from dyes under the action of external magnetic fields.
