A simple catalyst-free route for large-scale synthesis of SiC nanowires

Chemistry of one dimensional silicon carbide materials: Principle, production, application and future prospects

“…A C C E P T E D ACCEPTED MANUSCRIPT 21 Chen et al [34] have fabricated SiCNWs on large scale by using a special carbon source with porous and loose structures. Expandable graphite (EG) is a graphite intercalation compound in which some oxidants, such as sulfuric acid, potassium permanganate, are inserted between the carbon layers of the graphite.…”

“…The formation of the loose and porous structures may be the key factor for the high yield of SiCNWs. As discussed in earlier section, Chen et al [34] have demonstrated bulk synthesis of SiCNWs using Expandable graphite (EG) and silicon powder. Fig.…”

“…The carbothermal reduction of silica [25][26][27] and hydrogen reduction of methyltrichlorosilane [28][29][30][31] are the two most widely used methods. The bulk production of 1D SiC nanostructures is a challenging issue which is currently being undertaken by different research groups [32][33][34][35][36][37][38]. Bulk production of 1D SiC nanostructures using carbothermal reduction of silica has been studied in detail.…”

Effective Synthesis of Silicon Carbide Nanotubes by Microwave Heating of Blended Silicon Dioxide and Multi-Walled Carbon Nanotube

“…This result is in good consistence with the XRD result of SiCNTs synthesized from the ratio of 1:3 (Figure 2 (b)) which shows high yield conversion of SiO 2 particles and MWCNTs to β-SiCNTs when blend of ratio 1:3 of SiO 2 particles and MWCNTs was used. Chen et al 39 revealed similar result where strong FTIR peak centered at 820 cm -1 corresponded to transverse optical photon vibration mode of Si-C bond was observed from the FTIR spectra of synthesized 3C-SiC nanowires.…”

Effect of Heating Duration on the Synthesis of Silicon Carbide Nanotubes by Microwave Heating of MWCNTs and Silica

“…This showed that SiCNTs were successfully synthesized for blends of MWCNTS and SiO 2 heated at 20, 40 and 60 min. Chen et al (2011) reported the similar FTIR absorption band of the Si-C stretching bond at wavelength of 800 cm -1 for SiC nanowires. The FTIR absorption band of C=C bond of MWCNTs and Si-O bonding of SiO 2 particles were observed at wavelength of 1676 and 1175 cm -1 as observed in the FTIR spectrum of SiCNTs synthesized at 20 min in Figure 6(a), indicating the heating duration of 20 min was insufficient for the complete formation of SiCNTs.…”
