Synthesis and photoelectrocatalytic performance of Sb2S3 nanorods from natural stibnite

Antimony trisulfide (Sb2S3) nanorods were successfully synthesized via hydrothermal method with the assistance of polyethylene glycol (PEG) and N,N-dimethylformamide (DMF), using natural stibnite as precursor. The effects of experimental parameters on the morphology and the properties of the obtained Sb2S3 were systematically studied, and the possible formation mechanism of Sb2S3 nanorods in the preparation process was also discussed. Phase, compositions, morphology and photoelectric properties of the products were investigated by a series of characterization methods. The photocatalytic activity of nano Sb2S3 on the degradation of methyl orange were investigated under the visible light irradiation. The results showed that the Sb2S3 nanoflakes formed after hydrothermal synthesis at 160℃ for 12 h, and the nanoflakes would transform into nanorods eventually after N2-annealing at 400℃ for 1 h. The obtained Sb2S3 nanorods with a single crystal structure are typically 2~3 μm in length, 100~200 nm in width, which are direct semiconductor with band gap of 1.66 eV. Photocatalytic degradation rate of the obtained Sb2S3 nanorods on methyl orange under visible light irradiation is higher than that of commercial Sb2S3, which is up to 87.6% after 60 min degradation, exhibiting obvious visible-light activity.

Abstract

Antimony trisulfide (Sb2S3) nanorods were successfully synthesized via hydrothermal method with the assistance of polyethylene glycol (PEG) and N,N-dimethylformamide (DMF), using natural stibnite as precursor. The effects of experimental parameters on the morphology and the properties of the obtained Sb2S3 were systematically studied, and the possible formation mechanism of Sb2S3 nanorods in the preparation process was also discussed. Phase, compositions, morphology and photoelectric properties of the products were investigated by a series of characterization methods. The photocatalytic activity of nano Sb2S3 on the degradation of methyl orange were investigated under the visible light irradiation. The results showed that the Sb2S3 nanoflakes formed after hydrothermal synthesis at 160℃ for 12 h, and the nanoflakes would transform into nanorods eventually after N2-annealing at 400℃ for 1 h. The obtained Sb2S3 nanorods with a single crystal structure are typically 2~3 μm in length, 100~200 nm in width, which are direct semiconductor with band gap of 1.66 eV. Photocatalytic degradation rate of the obtained Sb2S3 nanorods on methyl orange under visible light irradiation is higher than that of commercial Sb2S3, which is up to 87.6% after 60 min degradation, exhibiting obvious visible-light activity.
