Abstract

The invention provides a preparation method of nanometer copper sulfide, which is characterized in that the preparation method comprises the following steps: 1, adding sodium tripolyphosphate, folic acid and sulfur ion compound into deionized water to obtain solution A; 2, dissolving that copper ion compound in deionize water to obtain solution B; step 3: adding solution B to solution A dropwise under stirring conditions, and when the solution becomes a black-brown copper sulfide suspension, and continuously stirring for 20-40 minutes, obtaining nanometer copper sulfide suspension. The invention takes copper chloride dihydrate and sodium sulfide nonahydrate as raw materials to be synthesized in aqueous solution, has high efficiency and convenience, low equipment requirements, and no toxicdrugs and toxic solvents in the reaction process.

Description

technical field [0001] The invention relates to the technical field of nanometer materials, in particular to a method for preparing nanometer copper sulfide. Background technique [0002] Copper sulfide is one of the most important components of copper minerals, accounting for 80% of copper resources. Therefore, the research on copper sulfide has also received extensive attention. In industries such as supercapacitors, semiconductors, and medical treatment, copper sulfide has gradually shown its potential various applications. In recent years, copper sulfide has attracted great attention in the field of nanophotothermal therapy. Researchers have discovered in copper sulfide photothermal therapy that copper sulfide can not only realize photothermal conversion, but also have photodynamic properties induced by near-infrared light, and generate high concentrations of reactive oxygen species to kill tumor cells. [0003] At present, there are many methods for synthesizing nano...
