Macroscopic three-dimensional ultralight Fe3O4 doped graphene aerogel composite material and preparation method
The invention belongs to the technical field of functional materials and relates to a macroscopic three-dimensional ultralight Fe3O4 doped graphene aerogel composite material and a preparation method. According to the preparation method, firstly, expanded graphite powder is taken as a raw material, graphene oxide is prepared with an improved Hummers method, and ferric trichloride is thermally hydrolyzed to prepare ferric hydroxide colloid; secondly, the ferric hydroxide colloid is dropwise added into a graphene oxide solution, and a hydrothermal reduction reaction is performed to obtain Fe3O4 doped graphene aerogel; and finally, hydrothermal treatment by ammonia water and vacuum freeze-drying are performed to obtain the macroscopic three-dimensional ultralight Fe3O4 doped graphene aerogel composite material. In percentage by weight, the Fe3O4 content is 0-65% and the balance is graphene aerogel. The synthetic method for the Fe3O4 doped graphene aerogel composite material is simple, feasible, easy to control, small in specific gravity, large in surface area and outstanding in porous characteristic, and can be used in the fields of sewage treatment, stealth, biological medicines, new energy, electronic materials and the like.
