The method has the advanges of simple process, easiness in control and high production efficiency.

Description

technical field [0001] The invention relates to a three-dimensional spherical In 2 S 3 -SnS 2 Method for the preparation of the complex. Background technique [0002] In 2 S 3 It is a new type of optoelectronic material. It has been reported that three-dimensional spherical In 2 S 3 . This In 2 S 3 It has a large specific surface area and exhibits certain photoelectric conversion and catalytic properties. This three-dimensional spherical structure is also an ideal composite carrier, because its surface has many pores of tens of nanometers, which can be easily combined with other nanoparticle materials. Its composites tend to have better photoelectric conversion and catalytic properties. SnS 2 It is a kind of flake nanomaterial, and it has not been reported that three-dimensional spherical In 2 S 3 -SnS 2 complex, applicants found that mainly because of the SnS 2 The side length of the nanosheet is 50-100nm, it is difficult to enter the In 2 S 3 channel, so w...
