Bi2S3 nanomaterials: morphology manipulation and related properties

Abstract

The Bi₂S₃ nanomaterials with various morphologies such as nanorods, nanowires, nanowire bundles, urchin-like microspheres and urchin-like microspheres with cavities have been successfully synthesized through a simple hydrothermal method. Experimental results indicate that sulfur sources play crucial roles in determining the morphologies of Bi₂S₃ products. Moreover, formation mechanisms of different Bi₂S₃ nanostructures are discussed based on understanding of the growth habit of Bi₂S₃ crystal. Finally, we also studied the morphologies-dependent electrochemical and optical properties of the as-synthesized Bi₂S₃ nanomaterials.
