Abstract:

Fe3O4/rGO nanocomposites were prepared by hydrothermal method using Fe(OH)3 as precursor of magnetite nanoparticles, graphene oxide (GO) as precursor of reduced graphene oxide (rGO), hydrazine and trisodium citrate as mixed reducing agent. The morphologies, structures and compositions of the products were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and thermogravimetric analysis (TGA). The electrochemical characteristics of assembled coin-type cells versus metallic lithium were evaluated by cyclic voltammetry and galvanostatic charge-discharge. The uniform morphology, high reductive level of rGO and the role of rGO buffering the volume changes of Fe3O4 nanoparticles in the charging-discharging process can be responsible for the good electrochemical performance of Fe3O4/rGO nanocomposites.
