Direct sulfidization synthesis of high-quality binary sulfides (WS2, MoS2, and V5S8) from the respective oxides

Synthetic Fabrication of Nanoscale MoS2-Based Transition Metal Sulfides

“…prepared polycrystalline MnS, FeS 2 , and amorphous sulfur-rich sulfides of Cr, Mo and W by the reaction of the transition-metal carbonyls with sulfur in 1,2-dichlorobenzene [65]. High quality binary sulfides of WS 2 , MoS 2 , and V 5 S 8 have been prepared via a direct sulfurization route from the respective oxides via (hydro)solvothermal syntheses [66]. The produced MoS 2 has a flower-like morphology with an average diameter of 400 nm, the surface of which composed of nanoflakes with a width of ca.…”

“…The produced MoS 2 has a flower-like morphology with an average diameter of 400 nm, the surface of which composed of nanoflakes with a width of ca. 20 nm (Figure 2) [66]. …”

Thermal conversion of tungsten oxide nanorods to tungsten disulfide nanoflakes

“…So far, nanostructured WS 2 materials such as nanotubes, nanoplates, nanoflowers, fullerene-like nanoparticles, etc. have been synthesized by some methods including gas-solid or gas phase reactions [12][13][14][15][16], sonochemical synthesis [17,18], pulsed laser technique [19,20], hydrothermal/solvothermal route [21][22][23] and fluidized-bed reactor synthesis [24]. Recently, tungsten oxide nanorods were found to be effective precursors in the synthesis of WS 2 nanotubes.…”

A low-temperature extraction–solvothermal route to the fabrication of micro-sized MoS2 spheres modified by Cyanex 301

“…Xu [18] reported the preparation of MoS 2 hollow spheres with diameter of 400-600 nm via the reaction of (NH 4 ) 6 Mo 7 O 24 and thioacetamide with Fe powder as the reducing agent. Chen [19] obtained spherical MoS 2 with average diameter of 400 nm via a direct sulfidization of the oxides, using the formed H 2 S from the reaction of NH 3 Á H 2 O and CS 2 at 500 1C. Afanasiev [20] prepared MoS 2 hollow spheres with uniform size of 200-300 nm from the solution reaction of the common precursor (NH 4 ) 2 Mo 2 O 12 .…”
