Abstract

The invention discloses a preparation method of solid cubic blocky copper sulfide, and the method takes CuCl2. 4H2O as a copper source reactant, and takes biological small molecular L-methionine as asulfur source reactant and a structure directing agent. The copper sulfide powder which is uniform in particle size distribution and has high stability and optical characteristics is prepared by controlling the unique proportioning relationship between the two reaction raw materials, the unique proportioning relationship between the solvents and conditions in the reaction process. The method is simple in process, simple and convenient to operate, relatively mild in reaction condition, high in safety and reliability and relatively low in raw material cost. The micron-sized cubic solid copper sulfide prepared by the method has potential application in the aspects of light absorption materials, superconducting materials, detectors, sensors and the like.

Description

technical field [0001] The invention relates to the technical field of preparation of functional materials, in particular to a preparation method of solid square copper sulfide. Background technique [0002] Transition metal sulfides are a kind of special semiconductor materials with both physical and chemical functions. Among them, copper sulfide (CuS) is the most representative, which is a p-type semiconductor material with excellent optical, electrical and catalytic properties, and is widely used in gas detectors, ultrasensitive non-enzymatic glucose sensors, cold cathode emitters, etc. , switches, solar cells and superionic materials have a wide range of applications. In recent years, with the reduction of material size, micro-nano materials will also show unique properties, such as: quantum size effect, small size effect, surface and interface effect, quantum tunneling effect, etc. At present, there are many methods for preparing copper sulfide materials, such as hydr...
