摘要：A one-pot solvothermal reaction was used to prepare graphene/Fe3O4 composites using graphite oxide and FeCl3 center dot 6H(2)O as starting materials. Graphene oxide was reduced to graphene and the Fe3O4 microspheres were simultaneously grown on the carbon basal planes under the conditions generated in the solvothermal system. The product showed a high crystallinity of magnetite and a considerable saturation magnetization. The size and density of the Fe3O4 microspheres distributed on the graphene can be easily controlled by altering the starting Fe3+ concentration. Doxorubicin hydrochloride was loaded on to the graphene/Fe3O4 composites by simple mixing, and a saturation loading capacity as high as 65% could be achieved.
