Abstract

Bismuth sulfide (Bi₂S₃) nanostructures with various morphologies, including nanowires, nanorods and nanoflowers, have been successfully fabricated via a facile hydrothermal method. The results show that the sulfur source plays a crucial role in determining the product morphology. Photocatalysis experiments show Bi₂S₃ nanowires exhibit the highest photocatalytic reduction of Cr(VI) when exposed to visible light irradiation.
