- Abstract
Tungsten disulfide (WS2) nanomaterials have unique two-dimensional nanostructures. Conventional flake-like tungsten disulfide crystals are composed of unit layers consisting of S=W=S. In recent years, the research of two-dimensional layered materials has attracted the attention of scientists, especially the rapidly developing graphene nanomaterials, which have the characteristics of high strength, excellent conductivity and thermal conductivity, and are widely used in the field of sensors. Due to the anisotropy of WS2 structure, different morphologies have significant effects on its performance. Therefore, it is of great theoretical and practical significance to explore and expand new preparation methods and process parameters of WS2, to achieve micro-structure, morphology and micro-scale control preparation, and to make it applied in a wider range of fields. Low-dimensional tungsten disulfide nanomaterials were prepared by hydrothermal method, and their growth mechanism was studied. Their ultraviolet-visible absorption optical properties were tested. The experimental results show that the tungsten disulfide nanofibers prepared by hydrothermal method have high specific surface area and excellent optical absorption characteristics, and have wider, potential and application prospects.
