Abstract
A composite of graphene (GE) supported by rod-like Fe3O4 nanocrystals has been fabricated by a simple one-step chemical route. X-ray diffraction and transmission electron microscopy results show that the Fe3O4 nanorods with diameters in the range of 15–20 nm and lengths of 150–200 nm were firmly assembled on the GE nanosheet surface. Magnetic property investigation indicated that the Fe3O4/GE composites exhibit a ferromagnetic behavior and possess a saturation magnetization of 50.11 emu g−1. Moreover, Fe3O4/GE composites showed a very high adsorption capacity of Congo red.
