Nanostructured metal sulfide–amine hybrid materials have attracted attention because of their unique properties and versatility as precursors for functional inorganic nanomaterials. However, large-scale synthesis of metal sulfide–amine hybrid nanomaterials is limited by hydrothermal and solvothermal preparative reaction conditions; consequently, incorporation of such materials into functional nanomaterials is hindered. An amine molecule-assisted refluxing method was used to synthesize highly uniform zinc sulfide⋅(diethylenetriamine)0.5 (ZnS⋅(DETA)0.5) hybrid nanosheets and nanobelts in a large scale. The obtained ZnS⋅(DETA)0.5 hybrid nanomaterials can be used as efficient precursors to fabricate functional ZnS nanomaterials and carbon encapsulated sulfur (S@C) nanocomposite cathodes for Li–S batteries. Semiconducting hybrid nanomaterials for sulfur nanocomposite cathodes were prepared by an amine molecule-assisted refluxing technique. Uniform zinc sulfide⋅(diethylenetriamine)0.5 hybrid nanomaterials were synthesized in a 15 g yield per one-pot reaction. The material was used to fabricate functional zinc sulfide nanomaterials and encapsulated sulfur nanocomposites.
