“…Inorganic nanotubes and inorganic fullerene-like (IF) structures of WS 2 were first discovered by Tenne et al in 1992 [1], which has opened a challenging field for the synthesis and applications of numerous such layered structures, such as WS 2 [1], MoS 2 [2,3], BN [4], NiCl 2 [5], and etc. Various synthesis methods have been reported, such as the microwave treatment of W(CO) 6 (Tungsten carbonyl) reacting with H 2 S (hydrogen sulphide) [6], ultrasonic irradiation of W(CO) 6 solution mixed with diphenylmethane and sulphur followed by heating at 800 °C [6], commercial WS 2 activation [7], iodine transport method [8], direct pyrolysis of WS 4 2− and CTAB (Cetyltrimethyl Ammonium Bromide) [9], and chemical vapour deposition [10]. Recently, IF-WS 2 nanoparticles and nanotubes have also been obtained from WCl n and WO x Cl y reacting with H 2 S [11].…”

This manuscript demonstrates the design, modification and initial investigation of a rotary furnace for the manufacturing of inorganic fullerene WS 2 nanoparticles. Different preparation methods starting with various precursors have been investigated, of which the gas-solid reaction starting with WO 3 nanoparticles was the most efficient technique. Furthermore, the influence of temperature, reaction time, and reaction gases etc. on the synthesis of inorganic fullerene WS 2 nanomaterials was investigated, and these parameters were optimised based on combined characterisations using XRD, SEM and TEM. In addition, the furnace was further modified to include a baffled tube, a continuous gas-blow feeding system, and a collection system, in order to improve the batch yield and realise continuous production. This technique has improved the production from less than 1 g/batch in a traditional tube furnace to a few tens of g/batch, and could be easily scaled up to industry level production.

“…Many nanowires and nanotubes, such as SiC, GaN, Si, Ge, Ga 2 O 3 , SnO 2 , WS 2 , MoS 2 and V 2 O 5 , have been synthesized [2][3][4][5][6][7][8][9][10]. Recently, an important nanostructured group, nanobelts, which is distinctly different from hollow nanotubes [11] and solid nanowires [12,13], has been successfully fabricated by simple evaporation.…”

“…5 These nanotubes have an average outer diameter of about 25 nm. MoS 2 and WS 2 nanotubes have also been synthesized by chemical transportation using iodine as the transport agent, [6][7][8] by the activation method ͑acid treatment following by sonication͒, 9 and by template synthesis. 10 The yield of nanotubes usually is in the range of 15-20% by these approaches.…”
