摘要：

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)(2)CO3 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. (c) 2006 Elsevier B.V. All rights reserved.
