Embodiment 1
[0036] 1. SnS 2 Synthesis of / PPy composites:
[0037] 1) Flower SnS 2 Synthesis of : Weigh 2 mmol SnCl 4 ·5H 2 O was dissolved in 30 ml of ethanol, magnetically stirred to dissolve it, 5 mmol of thioacetamide was added, and after magnetic stirring for 2 hours, it was transferred to a stainless steel autoclave with a volume of 50 ml of polytetrafluoroethylene lined, and sealed. , heated at 200°C for 24 hours, naturally cooled to room temperature, and the resulting precipitate was centrifuged, washed and dried.
[0038] 2) SnS 2 Synthesis of / PPy composites: 25 mg of pyrrole (Py) monomer was dissolved in 200 ml of water, followed by adding 500 mg of the above solvothermally synthesized flower-like SnS 2 powder, magnetically stirred for 1 hour to make it evenly dispersed, then irradiated with xenon lamp for 5 hours, the solid product was centrifuged, washed and dried to obtain SnS 2 / PPy composite.
[0039] The composition of the product was analyzed by a British Renishaw...
