【 摘 要 】

A facile, ionic liquid-assisted route was developed to synthesize hierarchical CuS flower-like submicrospheres at 80°C for 24 h. The method was based on a reaction between CuCl₂ and thioacetamide (TAA) in aqueous solution with using ionic liquid 1-ð‘�??-butyl-3-methylimidazolium chloride ([BMIM]Cl) as an assisted agent. The chemical composition, morphology and size of CuS product were characterized by XRD, SEM and TEM. The result shows that the as-prepared CuS consists of flowery spheres with a diameter of 0.6 ∼ 1.0 𝜇m, and these submicrospheres are, in fact, built by numerous nanoflakes with a thickness of 10 ∼ 20 nm. The optical property of CuS product was examined by UV-Vis. In general, we suggested an ecologically and environmentally friendly route for the syntheses of hierarchical metal chalcogenides structures in this paper.
