Description
Technical Field
The invention belongs to the technical field of nano materials, and particularly relates to a preparation method of nano copper sulfide.
Background
Copper sulfide accounts for 80% of copper ore resources, and has been attracting attention as a main copper mineral. The nano copper sulfide has been widely applied in the fields of photocatalysis, capacitors, semiconductors, lithium batteries and the like. Meanwhile, in recent years, copper sulfide has attracted a great deal of interest in tumor diagnosis and treatment due to its strong near infrared absorption plasmon resonance absorption effect and low toxicity. If the copper sulfide is used for treating tumors by a photothermal method, high-concentration active oxygen clusters can be generated to kill tumor cells according to the characteristics of high photothermal conversion and near infrared light induced photodynamic of copper sulfide nanocrystals.
At present, most of the synthesis methods of nano copper sulfide use toxic chemical reagents, such as a method for preparing nano copper sulfide by adding sodium sulfide or thioacetamide into a copper salt solution. Sodium sulfide is easily deliquesced in the air, and the released hydrogen sulfide gas can generate toxic effect on human bodies. Thioacetamide itself belongs to carcinogen, and acidic conditions used in the process of preparing the nano copper sulfide can also release hydrogen sulfide gas which is harmful to human bodies. Therefore, how to make the synthesis process safer and more environment-friendly is a problem that relevant researchers are continuously working on.
Hair from human and animals is a sulfur-containing material (containing about 5% of sulfur) which is produced in enormous quantities and is often treated as waste by human beings, and mainly comprises 19 to 22 kinds of amino acids (keratin), and the amino acids are naturally combined into a sulfur chain, and a disulfide bond in the sulfur chain is broken under high temperature, high pressure and strong alkali conditions to generate a mercapto group, which can be further combined with copper ions under strong alkali conditions to form nuclei to generate nano copper sulfide. Therefore, the animal hair can be used as a novel sulfur source to replace the traditional toxic sulfur source to prepare the copper sulfide, which is an important innovation for preparing the nano copper sulfide.
