摘要

Novel copper sulfide (CuS) hollow spheres composed of nanoflakes were synthesized under hydrothermal conditions by treating copper (Ⅱ)-thiourea complex from CuSO_4·5H_2O and thiourea at 180℃ for 24 h. When increasing the reaction temperature, much smaller hexagonal CuS nanoflakes generated from copper (Ⅱ)-thiourea complex formed and self-assembled into hollow spheres. The products were characterized by means of X-ray powder diffraction scanning electron microscopy and field emission scanning electron microscopy. It is found that the reaction temperature and copper (Ⅱ)-thiourea complex are of importance to form hollow spherical superstructures. A possible mechanism is also discussed.
