In recent years,as a type of graphene-like material with adjustable band gap,transitional metal sulfide has attracted increasing attention from researchers.Two-dimensional tungsten disulfide (WS2) nanomaterials are typical representatives of the transition metal sulfide family.Due to their characteristics of multiple active sites,high specific surface area,chemical stability and semiconducting properties,they have broad application prospects in electronic devices,electrocatalysis,biosensing and other fields.In this paper,combined with domestic and foreign researches in recent years,five main methods for preparing two-dimensional WS2 nanomaterials were reviewed,which included chemical vapor deposition,hydrothermal method,mechanical stripping method,ion intercalation stripping method and liquid-phase synthesis.The advantages and disadvantages of these methods were summarized,and it was pointed out that it was an urgent challenge to develop a preparation method of two-dimensional WS2 nanomaterials with high efficiency,high crystallinity and controllable layer number.
