Industrial Applications of Molybdenum disulfide
| Industry | Application | Process |
|---|---|---|
| Lubricants | Solid lubricant for friction components operating under high-temperature, high-pressure, high-vacuum, or corrosive conditions | Incorporated into lubricating oils or greases, or directly applied via spraying or sintering onto metal surfaces to form a lubricating film |
| Electronics & Semiconductors | Two-dimensional material for field-effect transistors (FETs), photodetectors, and flexible electronic devices | Preparation of monolayer or few-layer MoS₂ thin films via chemical vapor deposition (CVD), mechanical exfoliation, or liquid-phase exfoliation |
| Catalysis | Active component of hydrodesulfurization (HDS) catalysts for petroleum refining | Supported on carriers such as γ-Al₂O₃ and sulfided to form Co-Mo-S or Ni-Mo-S active phases |
| Composites | Reinforcing filler to enhance wear resistance, thermal conductivity, and antistatic properties of polymer-based composites | Dispersion of MoS₂ nanosheets into resin matrices via melt blending, solution blending, or in-situ polymerization |
| Batteries | Anode material for lithium- and sodium-ion batteries, offering high theoretical specific capacity | Synthesis of MoS₂ nanostructures (e.g., nanoflowers, microspheres) via hydrothermal, solvothermal, or calcination methods; combined with carbon materials to improve electrical conductivity |
| Coatings | Wear-resistant, self-lubricating protective coatings for aerospace and precision mechanical components | Deposition of MoS₂-based coatings using physical vapor deposition (PVD), magnetron sputtering, or thermal spray techniques |
Manufacturing Quality Control of Molybdenum disulfide
| Detection Item | Common Detection Methods | Method Overview |
|---|---|---|
| Purity/Main Component Content | X-ray Fluorescence Spectroscopy (XRF) | Utilizes X-rays to excite elements in the sample, generating characteristic fluorescence to rapidly determine the content of elements such as molybdenum and sulfur for purity assessment. |
| Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) | After dissolving the sample, it is nebulized into a high-temperature plasma; quantitative determination of molybdenum and other metal impurities is achieved by measuring the intensity of characteristic spectral lines. | |
| Impurity Element Content | ICP-MS (Inductively Coupled Plasma Mass Spectrometry) | High sensitivity enables detection of trace impurity elements (e.g., Fe, Cu, Ni, Pb) at ppb levels, suitable for impurity analysis in high-purity MoS₂. |
| Phase Structure | X-ray Diffraction (XRD) | Analyzes crystal structure to confirm whether the phase is 2H-MoS₂ or 3R-MoS₂, and detects the presence of impurity phases such as MoO₃. |
| Surface Morphology and Particle Size | Scanning Electron Microscopy (SEM) | Observes particle morphology, agglomeration state, and surface features; combined with Energy Dispersive Spectroscopy (EDS) for micro-area elemental analysis. |
| Particle Size Distribution | Laser Diffraction Analysis (LDA) | Measures particle size distribution based on laser scattering principles; applicable to dry powders or suspension samples, reflecting product uniformity. |
| Specific Surface Area | BET Specific Surface Area Method (Nitrogen Adsorption) | Calculates specific surface area from nitrogen adsorption-desorption isotherms, reflecting material dispersibility and the number of active sites. |
| Layered Structure and Number of Layers | Transmission Electron Microscopy (TEM) | High-resolution imaging enables observation of MoS₂ layer number, lattice fringes, and defects, suitable for nano-scale structural characterization. |
| Chemical Bonds and Functional Groups | Raman Spectroscopy | Characteristic peaks (e.g., E²g and A₁g modes) can determine layer number, crystallinity, and presence of defects or doping. |
| Thermal Stability | Thermogravimetric Analysis (TGA) | Monitors mass changes during heating to evaluate the onset temperature of oxidation and volatile content, assessing thermal stability. |
| Moisure and Volatile Content | Karl Fischer Method / Thermogravimetric Method | The Karl Fischer method precisely measures water content; TGA can determine total volatile content. |
| Electrical Conductivity (for specific applications) | Four-Point Probe Method | Measures resistivity of thin films or pressed samples to evaluate electrical properties, suitable for electronic-grade MoS₂ materials. |
