Low-temperature synthesis of uniform Sb2S3 nanorods and its visible-light-driven photocatalytic activities

Antimony sulfide (Sb2S3) nanorods with uniform size were prepared by the decomposition of Sb(C7H7OCSS)3 in N,N-dimethylformamide solution at 80 °C. The as-prepared Sb2S3 was orthorhombic phase and consisted of nanorods with the typical lengths in the range of 200–500 nm and the average diameter of ca. 30 nm. The photocatalytic experiment by degrading methyl orange in aqueous solution under visible light indicated that the activity of the dispersed Sb2S3 nanorods was better than that of Sb2S3 superstructures aggregated by nanorods.
