Magnetic-Graphene-Based Nanocomposites and Respective Applications
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 (Fe2O3, Fe3O4), ferrites MFe2O4, 3D graphene aerogels@hierarchical Fe3O4 nanoclusters, single-molecule magnets like TbPc2 (Pc: phthalocyanine), other organometallic-containing composites (benzene-metal-graphene), as well as polycomponent nanocomposites such as Ag/Fe3O4/G (G: graphene), Fe3O4/CdS/G, or FePc/Fe3O4/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.
