摘要：

Bi2S3 hierarchical columniform structures assembled by nanorod-built lamellae have been first synthesized by a simple wet chemical method through the reaction between Bi(NO3)(3)center dot 5H(2)O and CS2 at 80 degrees C for 14 h using DMSO as solvent without any surfactants. These new Bi2S3 structures were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscopy (SEM). Compared to ethylene glycol and DMF, DMSO supplied an excellent chemical environment favorable to the generation of Bi2S3 quickly in heterogeneous condition. The influences of the synthetic parameters were discussed and a possible growth mechanism for the formation of these complex structures was proposed. (C) 2009 Elsevier B.V. All rights reserved.
