Description

technical field [0001] The invention relates to the technical field of nanomaterials, relates to a ternary transition metal sulfide nanomaterial and a preparation method thereof, in particular to a Cu 2 MoS 4 Ternary nanomaterials and their preparation methods and applications, especially related to a ternary transition metal sulfide Cu 2 MoS 4 Its preparation method and application. Background technique [0002] In recent years, nanomaterials have developed vigorously. Since its size is close to the coherence length of electrons, its properties have changed greatly due to the self-organization brought about by strong coherence. Therefore, the properties exhibited by it, such as melting point, magnetism, optics, thermal conductivity, electrical conductivity, etc., are often different from those exhibited by the substance in its bulk state. [0003] Among them, compound semiconductor nanomaterials, due to the photoelectric properties of compound semiconductors themselves,...
