Review Molybdenum Disulfide for Different Applications -A Review
Pakistan Journal of Scientific & Industrial Research Series A: Physical Sciences
MoS2 is a layered evolution metal having similar structure to graphene. It has got universal consideration due to its different applications as sensors, energy storage devices, energy adaptation and environmental remediation. The properties of MoS2 and graphene are almost comparable but MoS2 has higher tendency than graphene because it has a low cost, tunable band gap and good visibility for light absorption properties. So, our main focus is to elaborate the up-to-date advances of MoS2 with respect to applications of energy and environment at broad area, for example, applications in HER, Li-ion battery, dye sensitized soar cells and super capacitors. At last the submission of energy and environmental for challenges to design MoS2 are painted. But MoS2 also has some limitations as a good photo catalyst which are discussed in this review article. In this study, we systematically explore the recent researches on transition metal doped MoS2 as photo catalyst for hydrogen evolution by ...

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 o C. 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 nextgeneration optoelectronic and photonic devices.

Studies to develop high activity MoS2: crystallography, thermal analysis and catalytic activity
2007
Nowadays environmental restrictions set the organosulfur compounds content of transport fuel up to 10 ppm. Ultra low sulfur diesel is obtained by deep hydrodesulfurization process. The commercial catalysts are nickel or cobalt promoted Mo/WS2 supported over alumina. Several methods to produce the catalysts are known and it has been observed that carbon content influences over improved activity and selectivity. This work was devoted to determine the crystal structures and to study the thermal behavior of a serie of tetraalkylammonium thiomolybdates and tungstates as precursors of Mo/WS2. Also the promoter containing compounds of Co/Ni(diethylenetriamine)2MoS4 were studied. Thermal decomposition reactions of the compounds were determined by the DTA-TG-MS method. Several molar ratios of blends of tetrapropylammonium thiomolybdate and nickel containing precursors were decomposed to obtain promoted MoS2. The catalyst was tested by the HDS of DBT showing the double activity of a comercial...
Synthesis of Nanostructured Molybdenum Disulfide by Chemical Vapour Deposition
Materials Today: Proceedings, 2017
Molybdenum disulfide (MoS 2) nanoparticles have been successfully synthesized using Chemical Vapour Deposition (CVD) technique. Inorganic precursors have been used to develop MoS 2 nanoparticles. A detailed study has been carried out to investigate the influence of process parameters on morphological structure of MoS 2 nanoparticles. The nanoparticles have been characterized by Scanning Electron Microscope (SEM) and Xray Diffraction (XRD) technique. Investigations revealed that the temperature plays an important role in obtaining desired morphology of MoS 2 nanostructures. Nanostructures of different morphologies like nanoparticles, nanorods and nanoplate have been synthesized at different temperatures. It was observed that nanopartciles of different morphologies can be synthesized at 800 °C itself using CVD technique. The dimensions of nanoparticles synthesized have been analyzed using SEM as well as Scherrer's equation using XRD results. The results of XRD and SEM are in close agreement with each other.

Molybdenum disulfide (MoS2), the second most thoroughly investigated two-dimensional material after graphene, has attracted considerable interest in energy storage applications owing to its exceptional qualities, including its unique crystal structure, low electronegativity, and high specific capacity. In this study, we showed that a simple ball-milling procedure causes significant improvement in the capacitive properties of the bulk MoS2 (BL-MoS2). We characterized the material before and after the milling process using X-ray diffraction (XRD) and a BET surface area analyzer to find the material’s structural, crystalline features, and surface area, respectively. We prepared electrodes of BL-MoS2 and ball-milled MoS2 (BM-MoS2) for electrochemical investigation. The charge storage characteristics were examined using cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy (EIS). The BM-MoS2 and BL-MoS2 have a specific capacitance of 11...
