“…According to the literature [8,[26][27][28][29][30] and our experimental results, it is believed that MoS 2 and WS 2 IF nanostructures are formed in vapor, and the growth is dominated by the vapor-solid (VS) mechanism. By heating the reactants directly to 850 8C, the chlorides (MoCl 5 or WCl 6 ) and S quickly evaporate and simultaneously react.…”

“…Reaction mechanism: Reported strategies for the synthesis of sulfides, [8,26,[28][29][30] especially the reactions between chlorides and a mixed gas of H 2 S and H 2 , [8,28] gives us a good understanding of the reaction mechanism of MoCl 5 /WCl 6 and S. In the well-known reaction of MoCl 5 and H 2 S/H 2 , H 2 is used as the additional reductant [Eq. (1)].…”

Atmospheric Pressure Chemical Vapor Deposition: An Alternative Route to Large‐Scale MoS₂ and WS₂ Inorganic Fullerene‐like Nanostructures and Nanoflowers

Large-scale MoS2 and WS2 inorganic fullerene-like (IF) nanostructures (onionlike nanoparticles, nanotubes) and elegant three-dimensional nanoflowers (NF) have been selectively prepared through an atmospheric pressure chemical vapor deposition (APCVD) process with the reaction of chlorides and sulfur. The morphologies were controlled by adjusting the deposition position, the deposition temperature, and the flux of the carrier gas. All of the nanostructures have been characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), and scanning electron microscopy (SEM). A reaction mechanism is proposed based on the experimental results. The surface area of MoS2 IF nanoparticles and the field-emission effect of as-prepared WS2 nanoflowers is reported.

In this paper, flower-like MoS 2 nanosheets microspheres were successfully synthesized by low temperature hydrothermal process using the precursors of sodium molybdate (Na 2 MoO 4 Á2H 2 O), thiourea (SC(NH 2 ) 2 ), oxalic acid (C 2 H 2 O 4 Á2H 2 O) and de-ionized water. The effects of oxalic acid concentrations and growth time on the morphology and crystallographic structure of MoS 2 nanosheets microspheres were investigated. The morphology, crystallographic structure, chemical composition of the flower-like MoS 2 nanosheets microspheres were investigated by using scanning electron microscope, X-ray diffraction, Raman spectrum, high resolution transmission electron-microscopy, and X-ray photoelectron spectroscopy, respectively. It is revealed that MoS 2 powders are composed of large, uniform flower-like microspheres, which are formed by several nanosheets gathering together perpendicular to the spherical surface. And the nanosheets are poly-crystallized hexagonal phase. The experiment results also show that the oxalic acid concentration in the precursors plays a key role on the diameter and crystalline of MoS 2 nanosheets microspheres. The formation mechanism of flower-like MoS 2 nanosheets microspheres was discussed.

“…One of the most promising TMD's, MoS 2 , presents a wide range of applications such as selective gas sensors 1,2 , catalysis 3-5 , lithium ion battery anodes 6 and field-effect transistors (FETs) with high mobility and current On/Off ratios 7, 8 . Several growth methods have been developed to prepare thin-layer MoS 2 , including micromechanical exfoliation [8][9][10] , electrochemical synthesis 11 and chemical vapour deposition [12][13][14][15] . Generally, these methods have benefits and some disadvantages.…”

A green and simple synthesis method based on a two-step chemical vapour deposition approach has been developed to synthesis transition metal dichalcogenides flakes. With non-toxic precursor such as transition metal oxides and elemental sulphur, large-area, strong photoluminescent, and uniform MoS 2 nanoflakes was produced at a relatively low growth temperature (650 °C). Controlling layer number and morphology was achieved only by precursor concentration without any oxide impurity revealed by SEM, PL and Raman spectroscopy. This method can be used to make wide range of metal chalcogenides such as ZnS, SnS 2 , PtS 2 and PdS 2 .
