Molybdenum Disulfide Properties

About Molybdenum Disulfide MoS2 Powder:
Molybdenum disulfide is an inorganic compound composed of molybdenum and sulfur. Molybdenum disulfide chemical formula is MoS2.
Like most mineral salts, Moly disulfide has a high melting point but begins to sublime at a relatively low 450ºC. This property is useful for purifying compounds.

This compound is classified as a transition metal dihalide. Moly sulfide is a silver-black solid in the form of molybdenite (the main ore of molybdenum). MoS2 is relatively unreactive. It is not affected by dilute acid and oxygen. In appearance and feel, molybdenum disulfide is similar to graphite. Because of its low friction and robustness, it is widely used as a dry lubricant. Bulk MoS2 is a diamagnetic, indirect bandgap semiconductor similar to silicon, with a bandgap of 1.23 eV.

In addition to its lubricity, MoS2 is also a semiconductor. It is also known that when doped with an electrostatic field, it and other semiconductor transition metal chalcogenides become superconductors on its surface.
MoS2 and related molybdenum sulfides are efficient catalysts for hydrogen evolution, including the electrolysis of water; thus, are possibly useful to produce hydrogen for use in fuel cells.

As in graphene, the layered structures of MoS2 and other transition metal dichalcogenides exhibit electronic and optical properties that can differ from those in bulk. Bulk MoS2 has an indirect bandgap of 1.2 eV, while MoS2 monolayers have a direct 1.8 eV electronic bandgap. supporting switchable transistors and photodetectors.

The sensitivity of a graphene field-effect transistor (FET) biosensor is fundamentally restricted by the zero band gap of graphene, which results in increased leakage and reduced sensitivity. In digital electronics, transistors control current flow throughout an integrated circuit and allow for amplification and switching. In biosensing, the physical gate is removed and the binding between embedded receptor molecules and the charged target biomolecules to which they are exposed modulates the current.

MoS2 also possesses mechanical strength, electrical conductivity, and can emit light, opening possible applications such as photodetectors. MoS2 has been investigated as a component of photoelectrochemical (e.g. for photocatalytic hydrogen production) applications and for microelectronics applications.

How is Molybdenum Disulfide MoS2 Powder produced?
MoS2 is naturally found as molybdenite (a crystalline mineral) or pyroxene (a rare low-temperature form of molybdenite). The molybdenite is processed by flotation to obtain relatively pure MoS2. The main pollutant is carbon. MoS2 can also be produced by heat treatment of almost all molybdenum compounds with hydrogen sulfide or elemental sulfur and can be produced by the metathesis reaction of molybdenum pentachloride.

Molybdenum Disulfide Uses:
Molybdenum disulfide is used as a dry lubricant in, e.g. greases, dispersions, friction materials and bonded coatings. Molybdenum-sulfur complexes may be used in suspension but more commonly dissolved in lubricating oils at concentrations of a few percent. MoS2 is used as additives in lubricating grease, friction materials, plastic, rubber, nylon, PTFE, coating and so on.

Advanced Solid Lubricants
Molybdenum disulfide is widely used as an excellent solid lubricant in advanced solid lubricants. Its layered structure allows it to maintain excellent lubricating properties at high temperatures and pressures. During the operation of machinery, molybdenum disulfide can form a protective film, reducing friction and wear between mechanical parts, improving mechanical efficiency and extending the service life of equipment. In the petroleum and chemical industries, molybdenum disulfide is often used as an additive to lubricating oils to significantly improve the lubricity and high temperature resistance of equipment.

Catalyst
Molybdenum disulfide is an excellent catalyst and can be used in many different catalytic reactions. Its layered structure and the similar electrical conductivity of metallic semiconductor materials make it highly active in electrocatalytic reactions. In fuel cells, molybdenum disulfide can be used as an electrocatalyst to promote the reaction of hydrogen and oxygen to produce electricity and water. In addition, molybdenum disulfide can be used in combination with precious metals as a loaded catalyst for catalytic reduction reactions, alkylation reactions and hydrogenation reactions.

Composite materials
The micro- and nanostructure of molybdenum disulfide can be used to reinforce high-performance composite materials. By compounding molybdenum disulfide with polymers, ceramics and other materials, composites with excellent mechanical properties, thermal stability and corrosion resistance can be prepared. These composites can be used in aerospace, automotive, electronics and other fields. In addition, molybdenum disulfide can be used to prepare high-performance materials such as transistors and integrated circuits.

Optical conductors and semiconductors displaying P- or N-type electrical conductivity
Molybdenum disulfide has excellent electrical conductivity and physicochemical properties and can be used as a photoconductor and semiconductor material. In photoelectric conversion devices, molybdenum disulfide can be used as a light-absorbing layer material to convert light energy into electrical energy. In addition, molybdenum disulfide can be used to manufacture devices such as field effect transistors and integrated circuits. Among them, transistors using molybdenum disulfide as a semiconductor material have been widely researched and applied in recent years.

Friction materials
Molybdenum disulfide can be used in friction materials to reduce and increase friction. Its layered structure and excellent physical properties enable it to form a protective film during the friction process, reducing frictional wear and oxidation. At the same time, molybdenum disulfide can also improve the thermal stability and corrosion resistance of friction materials and extend their service life. Molybdenum disulfide is widely used in the manufacture of high-performance friction materials in automotive, aerospace and other fields.

Electrode materials for lithium batteries
In recent years, molybdenum disulfide has been widely researched and applied as electrode material for lithium batteries. Its layered structure and high electronic conductivity enable it to improve the electrochemical performance and cycle life of electrodes in lithium batteries.
