Abstract

The present invention relates to a kind of ZnS-SnS 2 Method for the preparation of the complex. The inventive method will ZnCl 2 , oleic acid amide, thiourea, and water are mixed to form a precursor liquid, and placed in a hydrothermal reaction kettle for hydrothermal reaction to obtain nano-ZnS; nano-ZnS, SnCl 2 , thioacetamide, hydrazine hydrate and water are mixed to form a precursor solution, which is placed in a hydrothermal reactor for secondary hydrothermal reaction to obtain ZnS‑SnS 2 Complex. The method of the invention has the advantages of simple process, easy control and high production efficiency.

Description

technical field [0001] The present invention relates to a kind of ZnS-SnS 2 Method for the preparation of the complex. Background technique [0002] ZnS is a new type of photoelectric material, and it has been reported that nano-ZnS can be obtained by hydrothermal synthesis. This nano-ZnS has a large specific surface area and exhibits certain photoelectric conversion and catalytic properties. This nanostructure is also an ideal composite carrier, because of its large specific surface area, it can be easily composited with other nanoparticle materials. materials tend to have better photoelectric conversion and catalytic performance. SnS 2 It is a two-dimensional nanosheet material, and it has not been reported that ZnS-SnS can be obtained 2 Composite, the applicant found that the main reason is that ZnS is larger in size, which makes it difficult to combine with SnS 2 If the size of ZnS can be effectively reduced, it is expected to obtain ZnS-SnS 2 Complex. ZnS-SnS 2 ...
