| titleOfInvention | Magnetic graphene/ferroferric oxide/manganese dioxide nanocomposite and preparation and application thereof |
| abstract | The invention discloses a magnetic graphene/ferroferric oxide/manganese dioxide nanocomposite and a preparation method and application thereof, wherein the magnetic graphene/ferroferric oxide/manganese dioxide nanocomposite is prepared by the following steps: (1) dispersing graphene oxide and polyethylene glycol in purified water in a constant-temperature water bath, and ultrasonically forming a uniform suspension: (2) FeCl is added dropwise 3 And FeCl 2 Continuously reacting for 4-6 hours in an oxygen-free environment, then adding ammonia water to adjust the pH value to 10.5-11.5, raising the temperature of the water bath to 70-80 ℃, and continuously reacting for 2-3 hours to obtain a mixed solution; (3) adding MnSO into the obtained mixed solution 4 The solution was then KMnO added 4 And KOH, reacting for 2-4 hours, and then carrying out post-treatment to obtain the catalyst. The invention takes graphene sheet layers as carriers, and Fe is sequentially precipitated and grown on the graphene sheet layers in situ 3 O 4 And MnO 2 Nanoparticles to prevent agglomeration of graphene; meanwhile, the lamellar structure of graphene oxide is used as Fe 3 O 4 And MnO 2 Immobilization of nanoparticles to support against Fe 3 O 4 And MnO 2 And (4) agglomeration of the nano particles. The invention provides a nano composite materialThe method has the characteristics of environmental protection, rapidness, simplicity and convenience. |
