Abstract

The invention discloses a preparation method of a copper sulphide classified nanometer structure material. The method comprises the following steps of: uniformly mixing copper acetate, dimethyl sulfoxide and sublimed sulfur powder to react for 1-2 hours at 100-150 DEG C; and cooling, separating, washing and drying to obtain the copper sulphide classified nanometer structure material. The method has the advantages of mild reaction conditions, short reaction period, simple operation steps, good repeatability, less quantity of used raw materials, low toxicity, low-energy environment-friendly whole synthetic process, novel feature structure, controllability and the like. The invention also discloses the copper sulphide classified nanometer structure material, wherein the copper sulphide classified nanometer structure material is nest-shaped or multilayer disc shaped; and the feature of a product can be effectively adjusted by simply regulating reaction temperature and time so as to obtain the copper sulphide classified nanometer structure material with the nest-shaped or multilayer disc shaped feature; and the feature is novel in structure and uniform in structural size.

Description

technical field [0001] The invention relates to the field of inorganic nanometer materials, in particular to a copper sulfide graded nanostructure material and a preparation method thereof. Background technique [0002] In the past few decades, semiconductor nanomaterials have attracted the attention of many researchers due to their unique properties and wide range of applications. Copper sulfide is an important p-type semiconductor, which has great potential application value in the fields of photocatalysis, nonlinear optical materials, sensing, optoelectronics, thermoelectricity, and solar cells. [0003] So far, many nano-copper sulfide materials with different morphologies have been synthesized and reported, such as flower shape, spherical shape (hollow or solid), nanodisk shape, sea urchin shape, nanowire, tetradecahedron and so on. There are many methods for preparing nano-copper sulfide materials, such as solvothermal method, hydrothermal method, microwave-assisted m...
