Molybdenum disulfide is the inorganic compound with the formula MoS2. This black crystalline sulfide of molybdenum occurs as the mineral molybdenite. Natural amorphous form is known as more rare mineral jordisite. More so than other transition metal chalcogenides, MoS2 is unreactive, being unaffected by dilute acids. In terms of its appearance and feel, molybdenum disulfide is similar to graphite and indeed it is widely used as a solid lubricant due to its low friction properties, sometimes to relatively high temperatures.
MoS2 is diamagnetic and a semiconductor.
Molybdenum disulfide is often a component of blends and composites where low friction is sought. A variety of oils and greases are used, since they retain their lubricity even in cases of almost complete oil loss, thus finding a use in critical applications such as aircraft engines. When added to plastics, MoS2 forms a composite with improved strength as well as reduced friction. Polymers that have been filled with MoS2 include nylon, with the trade name Nylatron, Teflon, and Vespel. Self-lubricating composite coatings for high-temperature applications have been developed consisting of molybdenum disulfide and titanium nitride by chemical vapor deposition.
A research group headed by Prof. LI Can with the Dalian Institute of Chemical Physics has claimed that when combined with Cadmium sulfide it significantly increases the rate of photocatalytic Hydrogen production
