Hierarchical SnS2 hydro-thermal preparation method

The invention discloses a hierarchical SnS2 hydro-thermal preparation method. The hierarchical SnS2 hydro-thermal preparation method comprises the following steps of dissolving a plant phenolic acid in deionized water to obtain plant phenolic acid aqueous solution, and then adding, stirring and dissolving SnCl4-5H2O and thiourea in the plant phenolic acid aqueous solution to obtain a yellow liquid mixture; transferring the liquid mixture into a stainless steel hydro-thermal reactor with a Teflon liner, closing and heating the reactor at an appropriate temperature for a period of time, cooling down to room temperature, performing centrifugal separation to obtain solid matters, washing the solid matters in deionized water and ethanol for a number of times, and then vacuum-drying the solid matters at 60 DEG C to obtain nanoparticle-assembled and two-dimensional nanosheet-assembled flower-like hierarchical SnS2 materials. According to the hierarchical SnS2 hydro-thermal preparation method, the raw materials and a
