Abstract
Hollow CuS nanostructured microspheres with novel surface morphologies were synthesized by a facile precipitate-converting reaction. The products were characterized by SEM, XRD, BET measurements and size analysis. The surfaces of the hollow CuS microspheres showed acicular, rod-like, concavo-convex and flat morphologies respectively when using different amounts of thioacetamide as precipitants. The diameters of the hollow CuS microspheres could be tuned to a certain extent by using Cu 2(OH) 2CO 3 microspheres with different sizes as precursors. A solid–solution–solid mechanism for the formation of the hollow CuS nanostructured microspheres was discussed. The method reported here also could be applied for the synthesis of other nanostructured microspheres.
