Preparation of Fe₃O₄-doped magnetic graphene aerogels via radiation method in ethanol-H₂O solution

Abstract

The γ-ray irradiation method has been successfully used to prepare Fe₃O₄-Doped Graphene Aerogels(GA-Fe₃O₄-_ethanol) in Ethanol-H₂O solution. Electron microscopy and X-ray powder diffraction (XRD) techniques show that the graphene oxide was successfully reduced and showed a porous structure while Fe₃O₄ Nanoparticles are stably loaded on graphene. The material showed good adsorption stability in the process of repeatedly absorbing the organic solvent. At the same time, in the process of adsorbing organic solvents, it was noticed that the material has a certain elasticity in the organic phase, which is rarely seen in many other aerogel materials.
