Synthesis of Magnetic Carbon/Iron Oxide Nanocomposites in Ethylene Glycol/Water Mixed Solvents and Their Highly Adsorption Performance

The high ferromagnetism carbon/iron oxide nanocomposites were synthesized by the simple precursor and thermal calcination method. And the precursor was prepared by a microwave-assisted hydrothermal method in ethylene glycol (EG) and water mixed solvents. Furthermore, the morphologies, phases, and magnetic properties of the as-obtained carbon/iron oxide nanocomposites were discussed by changing the different solvents. The features of carbon/iron oxide nanocomposites were characterized by X-ray diffractometry (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and magnetic properties. The possible transformation mechanism of carbon/iron oxide nanocomposites are proposed. Meanwhile, the investigation of dye adsorption revealed that carbon/iron oxide nanocomposites exhibited excellent dye absorbability and substantial reusability. These results indicate that the carbon/iron oxide nanocomposites have potential applications in effective treating wastewater.
