“…Finally, the nuclear cores preferentially grew along the crystal plane (002) direction to form MoS 2 nanosheets. 32 On the basis of the literature, 33 the MoS 2 nanosheets assembled together and spontaneously aggregated into flower-like clusters in order to reduce the high surface energy. Therefore, MoS 2 clusters with flower-like shape were obtained when using pure distilled water as the solvent ( Figure 5A).…”

Molybdenum disulfide (MoS2) nanoparticles are widely used as oil additives for obtaining low friction and wear. In this article, MoS2 nanosheets with ultrathin shape and structure defects were prepared by a facile solvothermal method with the aid of polyethylene glycol (PEG 200). The products were analysed by X‐ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), X‐ray photoelectron spectroscopy (XPS), and Fourier transform infrared (FTIR). Results indicated that PEG 200 played a crucial role as the shape controller in the formation of different MoS2 structures. Interestingly, the prepared MoS2 perform excellent in improving the friction‐reducing and antiwear properties of oils. More importantly, the lubricating behaviour of the obtained MoS2 nanosheets as oil additives was still effective in the harsh condition of heavy load and high temperature. Further, the excellent lubrication performance of the prepared MoS2 was discussed based on the exfoliation into individually ultrathin nanosheets and nanosized debris, and the formation of MoS2‐based tribofilm inside the wear tracks.

“…XPS was used to analyze the chemical bonds on the surface of those samples, as shown in Supplementary Figure S1 and (Quinlan et al, 2016;Li et al, 2018b;Ni et al, 2018;Song et al, 2019;Yue et al, 2019;Han et al, 2020), respectively. The Mo 3 d and S 2s highly deconvoluted spectra of F-MoS 2 @NC-0.8 (Figure 3B) showed the three fitted peaks at 235.7, 232.5 and 229.4 eV are related to Mo 6+ −O, Mo 3d 3/2 and Mo 3d 5/2 (Feng et al, 2015;Ahn et al, 2018;Lei et al, 2018). It should be noted that the slight surface oxidation of MoS 2 could cause the existence of Mo 6+ −O.…”

Molybdenum sulfide (MoS2) has become a potential anode of lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs) due to its high theoretical capacity and low cost. However, the volume expansion, poor electrical conductivity and dissolution of polysulfides in the electrolyte during the cycling process severely limited its applications. Herein, few-layered MoS2@N-doped carbon (F-MoS2@NC) was synthesized through a facile solvothermal and annealing process. It was found that the addition of N-doped carbon precursor could significantly promote the formation of few-layered MoS2 and improve the performances of lithium and sodium storage. A high reversible capacity of 482.6 mA h g−1 at a high current density of 2000 mA g−1 could be obtained for LIBs. When used as anode material for SIBs, F-MoS2@NC hybrids could maintain a reversible capacity of 171 mA h g−1 at a high current density of 1,000 mA g−1 after 600 cycles. This work should provide new insights into carbon hybrid anode materials for both LIBs and SIBs.

In this study, molybdenum disulfide (MoS2) nanostructures were synthesized by a facile hydrothermal process, using ammonium heptamolybdate tetrahydrate ((NH4)6Mo7O24.4H2O) and thiourea (CH4N2S) as the reactants. The effects of experimental parameters including reaction temperatures and reaction times on the structure and morphology of MoS2 have primarily been investigated. The morphology, microstructure, chemical composition and optical properties of as‐synthesized MoS2 were characterized using field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM), energy dispersive X‐ray spectroscopy (EDS), X‐ray diffraction (XRD), Raman and Photoluminescence spectroscopy. The FESEM and TEM results indicate that depending on the reaction temperature, the three types of morphologies of MoS2 crystals could be obtained. Morphologies of MoS2 changed gradually from aggregated particles to flake‐like structure, then finally to nanosheet morphology with increasing reaction temperature from 160 to 220 oC. However, it was found that the reaction time contributed significantly to the restacking and refinement of MoS2 crystal structure, rather than affecting the morphology of the investigated samples. Both XRD and Raman investigations reveal that the as‐synthesized MoS2 has a hexagonal phase structure (2H‐MoS2). Interestingly, the as‐prepared MoS2 nanosheets exhibit photoluminescence in the visible range with the emitted photon energy of ~1.81 and ~1.95 eV, these properties make MoS2 a promising candidate as the material of choice for next‐generation optoelectronic and photonic devices.
