Molybdenum disulfide is a useful nanopowder needed for several applications in the field of nanotechnology. It belongs to the group of transition metals and is known for its unique molecular structure. Therefore, its properties are quite different and more useful compared to other materials used in several experiments of nanotechnology.

MoS2 is the formula of molybdenum disulfide, which consists of molybdenum and sulfur. Molybdenum is known to be one of the prominent transition metals. Thus, this metal sulfide is a compound with a unique structure of the hexagonal planes of sulfur atoms on either side of the hexagonal plane of the molybdenum atom. The crystalline particle forms due to the strong bonds between Mo and S atoms. Thus, the properties of MoS2 nanopowder are much different from other nanoparticles.

Special properties noted in MoS2 nanopowder

MoS2 is a molybdenite mineral that is found in nature in the form of bright, dark-shaded solid. The layers of this material easily slide over each other because of very low interlayer bonding, making it a good lubricant.

The emission of charged electrons from MoS2 results in the formation of negative trions, consisting of 2 electrons and a hole. The emission and absorption of these electrons occur in the highest number in PL or photoluminescence spectrum at room temperature. The optical nature of MoS2 is defined by the fact that the binding energy of trions is -40meV that is lesser than the binding energy of excitons that is 20 meV.



MoS2 is a super electrochemical compound that exhibits luminescence and semiconducting properties. Thus, it is used for biosensing probes while observing analytes. The quantum dots of MoS2 have zero dimension, with sizes less than 10 nm, which is termed inorganic fullerenes. These dots show high photoluminescence at some definite wavelengths, caused by the quantum confinement effect, making MoS2 a more efficient biosensor as per the fluorimetric style.

The monolayer of Molybdenum disulfide nanopowder can be formed by mechanical exfoliation or Scotch-tape method, which is also used to isolate the layers of graphene. Thus, thin layers of crystals are formed that can be separated due to weak interlayer bonds, which can stick to an inserted tape and peel off later. Thin films of MoS2 can also be formed by dissolving the crystals in an organic liquid, resulting in the formation of tiny flakes of 100 nm size. Intercalation is another way of exfoliating from solvent, where n-butyllithium is dissolved in a solution of hexane and water so that water reacts with lithium ions to release hydrogen and separate layers of crystals.
