Continuous Production of IF-WS2 Nanoparticles by a Rotary Process

Abstract

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.

A new method to prepare composite powders customized for high temperature laser sintering

“…1a and b. As previously discussed by Xu et al, the sample contains both multi-layered hollow core particles with and a minute amount of nanoplatelets [17].…”

“…NaCl (BioXtra grade with 99.5% purity) was purchased from Sigma Aldrich, UK. Full preparation details of the C-coated IF-WS 2 have been described in our previous papers [17,18].…”

Synthesis of WS2/CNT hybrid nanoparticles for fabrication of hybrid aluminum matrix nanocomposite

“…H 2 S gas as a source of sulfur has been used in CVD process in many research [13][14][15][16][17][18][19][20]. But H 2 S is very toxic and some researchers tried to remove it from the process [21][22][23][24][25][26][27][28][29].…”

Novel graphitic carbon coated IF-WS2reinforced poly(ether ether ketone) nanocomposites

“…Given the abundant amount of literature associated with carbon-based CNTs and graphene, [19][20][21] which can be used to assist in tackling the dispersion and interface issues, alternative carbon coated IF-WS 2 nanomaterials would therefore be very interesting to explore. Indeed, Xu et al have documented such IF-WS 2 @C nanoparticles, and importantly they have realised large-scale production by using a rotary tube furnace, 22 which makes investigation of such composites possible. Furthermore, the thermal stability of the IF-WS 2 @C nanoparticles (NPs) has been signicantly improved.…”
