“…It was reported that the mechanisms of gas-liquid-solid model [52], surface diffusion [53], gas phase nucleation [54], carbon dissolution model [55], and particle self-assembling growth [56] could be used to explain the formation mechanism of some of the carbon-coated metal nanoparticles. These mechanisms have some reference significance for the understanding of the formation mechanism of N-doped CSEINPs.…”

The N-doped composite shell encapsulated iron nanoparticles (CSEINPs) were prepared by DC arc discharge under nitrogen at 800°C, using the anode with high Fe content and good homogeneity. The morphology, microstructure, composition, and some properties of the N-doped CSEINPs were characterized by various characterization techniques. The results revealed that the shells of the N-doped CSEINPs were composed of homogeneously amorphous structure containing C, Fe, O, and N elements; the saturation magnetization (Ms) and coercivity (Hc) of them at room temperature were 130 emu/g and 194 Oe, respectively. Due to the surface structure and the electrostatic interaction, the N-doped CSEINPs are employed to remove methylene blue (MB) from the waste solution, and they exhibited high adsorption properties and photocatalytic activity under irradiation of visible light (IVL). The kinetics of adsorption of MB on the N-doped CSEINPs was investigated and the recycling test was carried out. The formation mechanism of the N-doped CSEINPs is discussed briefly.

“…This synthesis approach has also been applied using silicon. Using an arc discharge, silicon nanoparticles were synthesised in liquid nitrogen, nanoparticles and nanofibres in water, Si and SiO 2 nanoparticles were obtained using SiO and Ar gases, and Sn‐Si compositions were obtained with added Sn, and with the addition of aluminium and carbon, the core‐shell Si@Al 2 O 3 and Si@Al 3 C 4 nanoparticles were obtained . During the arc discharge between the graphite anode and the cathode covered with Si granules, in addition to the synthesis of nanoparticles, fireballs were also observed .…”

Composites based on graphene and nanosized silicon have recently been of interest in various applications. This paper reports a new method of synthesising a graphene-nano silicon composite material by spraying a mixture of quartz-graphite using an electric arc. The structure and composition of the materials obtained depends on the synthesis conditions. The quality of the graphene structure depends on the concentration of quartz in the load. Higher SiO 2 content leads to the production of more structured graphene. In this case, silicon is present in the materials in the form of carbide nanoparticles deposited on graphene planes. When sputtering pure quartz contained in the cavity of the graphite anode, silicon whiskers form during the synthesis process. The content of the silicon structure depends on the arc current and the sputtering rate of the anode material. The mechanisms that lead to the formation of the graphene structure and silicon whiskers in the condensation process of the products of the electric arc spraying of the anode material are considered.
