Novel CuS hollow spheres fabricated by a novel hydrothermal method

A thioglycolic acid (TGA) assisted hydrothermal process has been developed to synthesize submicron-sized copper sulfide (CuS) hollow spheres via the reaction between copper sulfate (CuSO4) and thioacetamide (CH3CSNH2). X-ray diffraction, transmission electron microscopy and scanning electron microscopy were employed to characterize the obtained product. Furthermore, the possible mechanism and the critical factors for the TGA-assisted hydrothermal synthesis of the CuS hollow spheres have been preliminarily presented.
