“…Graphene, the parent of all graphitic forms including fullerene, carbon nanotubes and graphite, is a two-dimensional building material for carbon materials of all other dimensionalities. Among them, hybrid of graphene and carbon nanotubes with Fe 3 O 4 NPs have been extensively studied in the fabrication of functional polymer composites, sensors, waste water treatment, catalysis and drug delivery Lim et al 2013;Yao et al 2012). It is believed that hybrid of magnetic NPs and graphene/graphene oxide (GO) would have better functionalities and performances in these applications (Georgakilas et al 2012;Kumar et al 2012;Zhu et al 2013).…”

Nanohybrid of graphene oxide (GO) and azidemodified Fe 3 O 4 nanoparticles (NPs) were fabricated using click reaction. First, Fe 3 O 4 NPs were modified by 3-azidopropionic acid. Then, click-coupling of azide-modified Fe 3 O 4 NPs with alkyne-functionalized GO was carried out in the presence of CuSO 4 Á5H 2 O and sodium L-ascorbate at room temperature. The attachment of Fe 3 O 4 NPs onto the graphene nanosheets was confirmed by Fourier-transform infrared (FTIR) spectroscopy, scanning electron microscopy, thermogravimetric analysis, energy dispersive X-ray spectrometry and X-ray diffraction spectrometry. As the FTIR spectroscopy and energy dispersive X-ray spectrometry analysis showed, the final magnetic graphene nanosheets were also reduced by sodium ascorbate which is a merit for click-coupling reactions. The specific saturation magnetization of the Fe 3 O 4 -clicked GO was 44.3 emu g -1 . The synthesized hybrid was used in the adsorption of methylene blue and congo red (CR). The adsorption capacities in the studied concentration range were 109.5 and 98.8 mg g -1 for methylene blue and CR, respectively.

Preparation, properties, and applications of magnetic-graphene-based nanocomposites are reviewed. Graphene magnetic nanocomposites include those on the basis of elemental metals (Fe, Co, Ni), magnetic nanoclusters, various morphological forms of iron oxides (Fe 2 O 3 , Fe 3 O 4), ferrites MFe 2 O 4 , 3D graphene aerogels@hierarchical Fe 3 O 4 nanoclusters, single-molecule magnets like TbPc 2 (Pc: phthalocyanine), other organometallic-containing composites (benzene-metal-graphene), as well as polycomponent nanocomposites such as Ag/Fe 3 O 4 /G (G: graphene), Fe 3 O 4 /CdS/G, or FePc/Fe 3 O 4 /GO (GO: graphene oxide), among others. Their available synthesis methods consist commonly of hydrothermal and solvothermal techniques, sol-gel autocombustion, sonoelectrochemical polymerization, thermal expansion and thermal reduction, microwave-assisted technique, and covalent bonding chemical methods. Their current and potential applications are distinct devices, in particular for colorimetric detection of glucose, construction materials, analytical, sensor and biosensor applications, environmental remediation, compounds with antibacterial properties, catalysis and photocatalysis, biological imaging, oil absorption, etc.
