Facile Synthesis, Structural, Morphological and Electrochemical Properties of Bismuth Sulfide (Bi2S3) Nanostructures.

ABSTRACT

Bismuth sulfide (Bi2S3) nanowires were synthesized successfully by a facile sonochemical method from Bi(DTC)3 as a single source precursor. The structural, vibrational, morphological properties and the functional groups of the samples were confirmed by powder X-ray diffraction (XRD), Fourier transform infrared (FT-IR), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) analysis and Raman spectroscopy techniques. The formation of pure phase of Bi2S3 and nanowires like morphology was confirmed by powder XRD and SEM analysis. The purity and elemental composition of Bi2S3 nanowires were confirmed by EDX analysis. The electrochemical properties of Catechol (CC) at the modified electrode were studied with the presence of Bi2S3 nanowires modified GCE electrode in aqueous solution with different scan rate and concentration. A novel method for determination of catechol using cyclic voltammetry (CV) was investigated. The homogeneous rate constants were estimated by comparing the experimental CV responses with the digital simulated results.
