Description

technical field [0001] The invention relates to a two-dimensional surface SnS 2 -MoS 2 Method for the preparation of the complex. Background technique [0002] SnS 2 It is a new type of photoelectric material. It has been reported that two-dimensional nanosheet SnS can be obtained by hydrothermal synthesis. 2 . This two-dimensional nanosheet SnS 2 It has a large specific surface area and exhibits certain photoelectric conversion and catalytic properties. This two-dimensional nanosheet structure 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. MoS 2 It is also a two-dimensional nanosheet material, and it has not been reported that two-dimensional surface SnS can be obtained 2 -MoS 2 composites, applicants found mainly because of the two-dimensional nanosheet MoS 2 Larger size, prone to curling...
