The chemical composition of tungsten disulfide (WS2) is clear and unique, consisting of two elements, tungsten (W) and sulfur (S), in a specific atomic ratio. Tungsten, as a transition metal, is located in Group VIB of the sixth period in the periodic table of elements, with an atomic number of 74. It has a complex and rich electronic configuration, which endows tungsten with multiple valence states and unique chemical activities. Sulfur, a typical non-metallic element, is in Group VIA of the third period, with an atomic number of 16. Its relatively high electronegativity makes it tend to gain electrons to achieve a stable electronic structure during the formation of compounds.
In tungsten disulfide, one tungsten atom combines with two sulfur atoms to form the basic unit. From the microscopic perspective of the crystal structure, each tungsten atom is closely surrounded by six sulfur atoms in an octahedral coordination manner, forming a stable structural motif. In this motif, the tungsten atom and sulfur atoms are connected by covalent bonds. This covalent bond originates from the strong orbital overlap between the valence electrons of the tungsten atom and those of the sulfur atoms, allowing the electron cloud to be shared between the atoms and thus forming a stable chemical bond. Each sulfur atom, in turn, is connected to three tungsten atoms, extending in a two-dimensional plane to form a hexagonal grid-like layered structure. Numerous such layered structures are stacked together through weak van der Waals forces, ultimately constructing the macroscopic crystal form of tungsten disulfide.
This chemical composition fundamentally determines many physical and chemical properties of tungsten disulfide. In terms of electrical properties, due to the electron cloud distribution between tungsten and sulfur atoms and the characteristics of covalent bonds, tungsten disulfide exhibits semiconductor properties. Electrons can move relatively freely within the layer, while their transmission between layers is hindered by van der Waals forces, resulting in obvious electrical anisotropy. In terms of chemical properties, tungsten disulfide can react with other substances under certain conditions. For example, in an environment with high temperature and the presence of an oxidant, sulfur atoms may be oxidized, thus changing the chemical composition and structure of tungsten disulfide and affecting its properties. In the field of catalysis, the specific active sites formed by its chemical composition enable tungsten disulfide to have a catalytic effect on certain chemical reactions, which can reduce the activation energy of the reaction and accelerate the reaction process. Moreover, by changing the preparation conditions, such as the ratio of raw materials, reaction temperature, and pressure, although the basic elements of the chemical composition remain unchanged, the arrangement of atoms, the defect situation of the crystal, etc. may change, significantly affecting the properties of tungsten disulfide and providing diverse possibilities for its applications in different fields.
