A kind of preparation method of dendritic copper sulfide microcrystal

Abstract

The invention relates to a preparation method of a dendritic copper sulphide microcrystal. According to the preparation method, cupric nitrate and thiamine hydrochloride serving as raw materials, deionized water serving as a solvent, and a preparing solution are subjected to hydro-thermal synthesis in a reaction kettle, and then are centrifugally separated, washed, extracted and filtered, and dried in vacuum to obtain a dendritic copper sulphide microcrystal product. The preparation method adopts the thiamine hydrochloride as a sulfur source, thus the dendritic copper sulphide microcrystal is green and nontoxic; and due to that the preparation process is advanced and reasonable, the data are full and accurate, the product has high purity up to 98%, the yield is high and up to 90%, no pollution is brought to the environment, the method is an ideal method for preparing the dendritic copper sulphide microcrystal.

Description

technical field [0001] The invention relates to a method for preparing dendritic copper sulfide microcrystals, belonging to the technical field of preparation and application of inorganic semiconductor micro-nano materials. Background technique [0002] Copper sulfide is a semiconductor material with excellent performance. It has good electrical conductivity and can be converted into a superconductor at low temperature. It has the characteristics of a fast ion conductor at high temperature; copper sulfide is also a P-type semiconductor material with a band gap of 2.0 ev is widely used in solar cells, sensors and catalysis. [0003] At present, the main methods for preparing copper sulfide include emulsion method, γ-ray radiation method, solvothermal method and hydrothermal synthesis method, but the sulfur sources involved in these methods are conventional sulfur sources such as thiourea, sodium sulfide, and sodium thiosulfate. These conventional sulfur sources will produce ...

[0003] At present, the main methods for preparing copper sulfide include emulsion method, γ-ray radiation method, solvothermal method and hydrothermal synthesis method, but the sulfur sources involved in these methods are conventional sulfur sources such as thiourea, sodium sulfide, and sodium thiosulfate. These conventional sulfur sources will produce toxic hydrogen sulfide gas, which will cause environmental pollution, and must be protected during preparation and use, which also hinders the preparation and application of copper sulfide
