As a typical representative of low-dimensional transition metal sulfide, molybdenum disulfide is a black powder composed of two chemical elements, transition metal molybdenum (atomic number 42) and nonmetallic oxygen (atomic number 8). It is also an inorganic compound with positive quaternary molybdenum ion (Mo4+) and negative divalent oxygen ion (O2-). It is the main component of molybdenite—Molybdenum disulfide, MoS2, 160.07 CAS login number 1317-33-5. In terms of physical and chemical properties, the appearance of molybdenum disulfide is a black powder with a metallic luster, melting point of 2375℃, density of 4.80g/cm³, Mohs hardness of 1.0 ~ 1.5, insoluble in water, acid solution (except aqua regans and hot concentrated sulfuric acid), alkaline solution and organic solvent, with good lubrication, semiconductor properties, reducing and oxidizing properties. The reducibility mainly manifests in that MoS2 will be oxidized, and molybdenum trioxide (MoO3) will be generated when heated to 400℃ in the air. Under heated conditions, MoS2 reacts with chlorine gas to form molybdenum pentachloride (MoCl5). The oxidation performance is mainly manifested in the decomposition of MoS2 into molybdenum and sulfur when heated to 1600℃ in a vacuum. In terms of structure, it has a layered structure similar to molybdenum diselenide, and each layer is composed of numerous hexagons. Cell parameters A and b are 0.329nm, c is 1.289nm, α and β are 90°, and γ is 120°.
