Abstract
A composite of graphene (GE) supported by rodlike Fe3O 4 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 Fe3O 4/GE composites exhibit a ferromagnetic behavior and possess a saturation magnetization of 50.11 emu g-1. Moreover, Fe 3O4/GE composites showed a very high adsorption capacity of Congo red.
