“…Tanaka et al [44] have recovered tungsten carbide nanoparticles after the pulsed discharge to tungsten wire in liquid paraffin. He et al [45] synthesized boron nitride nanosheet/nanotube-Fe nanocomposite via pulsed discharge of iron wire coated by boron nitride powder. Furthermore, several metal/metal oxide/graphene nanocomposites were also prepared through pulsed discharge of different metal wires in graphene oxide suspension [46,47].…”

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.

“…16 Therefore, the impact of BNNSs in association with other nanomaterials to produce nanocomposites with promising potential applications, such as sensors, energy storage, and catalysis, has captured the interest of some researchers. [17][18][19][20] For example, BNNSs supported on Au was theoretically suggested and experimentally proved to act as an electrocatalyst for the oxygen reduction reaction. 21 However, for photocatalytic activity, common BNNSs are considered to have no effect, because h-BN is an insulator with a wide band gap (3.6-7.1 eV depending on experimental methods).…”

Si quantum dots (QDs) have received quantities of attention owing to their multiple outstanding properties, such as the size-dependent optical property, photothermal property, electronic property, and biocompatible property. Therefore, researchers have been committed to exploring preparation methods of Si QDs. In this study, we have demonstrated a novel route to prepare Si QDs through a pulsed wire discharge method using Si strips. The as-prepared samples were recovered, centrifuged, and characterized by various techniques, such as XRD, Raman spectroscopy, SEM, TEM, FTIR, UV−vis absorption, and PL spectra. Consequently, the purified samples are confirmed to be pure Si QDs in a size of 1.4−4.7 nm, with an average particle size of 2.76−2.92 nm. Furthermore, the spectral analysis reveals the blue-emitting characteristics of the obtained Si QDs owing to the small particle size. Our studies demonstrate an efficient and cost-effective approach to produce colloidal Si QDs through pulsed wire discharge, which possesses potential for largescale production.
