“…Furthermore, several metal/metal oxide/graphene nanocomposites were also prepared through pulsed discharge of different metal wires in graphene oxide suspension [46,47]. In addition, several reports have been documented to use pulsed wire discharge to synthesize carbon nanomaterials, including fullerene [48,49], carbon nanotube [50,51], and amorphous carbon [52]. However, the synthesis of graphene materials with a sub-millimeter lateral size using pulsed wire discharge has rarely been reported.…”

The synthesis of large-size graphene materials is still a central focus of research into additional potential applications in various areas. In this study, large-size graphene platelets were successfully produced by pulsed discharge of loose graphite strips with a dimension of 2 mm × 0.5 mm × 80 mm in distilled water. The graphite strips were made by pressing and cutting well-oriented expanded graphite paper. The recovered samples were characterized by various techniques, including TEM, SEM, optical microscopy (OM), atomic force microscopy (AFM), XRD and Raman spectroscopy. Highly crystalline graphene platelets with a lateral dimension of 100–200 μm were identified. The high yield of recovered graphene platelets is in a range of 90–95%. The results also indicate that increasing charging voltage improves the yield of graphene platelets and decreases the number of graphitic layers in produced graphene platelets. The formation mechanism of graphene platelets was discussed. This study provides a one-step cost-effective route to prepare highly crystalline graphene platelets with a sub-millimeter lateral size.

“…He et al [18] synthesized boron nitride nanosheet/nanotube-iron nanocomposites by pulsed discharge of pure iron wire coated by boron nitride powders. Furthermore, electrical explosion of carbon fibers was used to synthesize fullerene [19,20] and carbon nanotubes [21,22]. More recently, graphene materials were obtained by electrical explosion of graphite sticks in distilled water [23].…”

One Step Preparation of Fe–FeO–Graphene Nanocomposite through Pulsed Wire Discharge

The Fe-FeO-graphene nanocomposite material was produced successfully by pulsed wire discharge in graphene oxide (GO) suspension. Pure iron wires with a diameter of 0.25 mm and a length of 100 mm were used in the experiments. The discharge current and voltage were recorded to analyze the process of the pulsed wire discharge. The as-prepared samples-under different charging voltages-were recovered and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy, and transmission electron microscopy (TEM). Curved and loose graphene films that were anchored with spherical Fe and FeO nanoparticles were obtained at the charging voltage of 8-10 kV. The present study discusses the mechanism by which the Fe-FeO-graphene nanocomposite material was formed during the pulsed wire discharge process.
