L-CYSTINE-ASSISTED SYNTHESIS OF BISMUTH SULFIDE NANORODS
摘要
Abstract
Nanostructured bismuth sulfide(Bi_2S_3) powder samples with different morphologies were synthesized by solvothermal method at 160℃ for 120 h using N, N-dimethylformamide (DMF), distilled water and distilled water-ethylene glycol (volume ratio 2:1) as the reaction solvent and Bi(NO_3)_3-5H_2O and L-cystine as the raw materials. The crystallinity, phase structure and morphology of the as-prepared samples were investigated by X-ray diffraction, energy dispersion spectroscopy, X-ray photoelectron spectroscopy, field-emission scanning electron microscopy and transmission electron microscopy. The results show the as-prepared Bi_2S_3 sample is typical Bi_2S_3 orthorhombic phase, and the diameters and lengths of nanorods of Bi_2S_3 synthesized in the DMF solvent are approximately 120 nm and 4-11μm, respectively. However, the Bi_2S_3 powder consists of nanoflakes when synthesis is carried out with distilled water and distilled water-ethylene glycol as the reaction solvent. The morphology and formation mechanism of Bi_2S_3 in different solvents are also discussed. A possible growth mechanism of one-dimensional nanorods is provided.关键词
