The Electronic Structure of Sb2S3 Wire and Its Application in Visible-Light-Driven Photodegradation of Methylene Blue

Abstract

Antimony trisulfide (Sb2S3) was studied from a theoretical and experimental perspective. Scanning electron microscopy (SEM), Raman scattering, UV-visible spectrophotometer, and X-ray diffraction (XRD) were used to analyze the morphological, optical, and structural characteristics. Three exchange-correlation functions (B3LYP, PBE0, and HSE06) and an all-electron basis set were used in the density functional theory (DFT) technique to estimate the vibrational frequencies, band gap, electronic structure, and structural geometry. The simulated findings agree with the existing experimental and theoretical knowledge. Finally, the degradation of MB under visible light irradiation was used to test the photocatalytic activity of Sb2S3 microwires. The findings show that Sb2S3 thin film promotes the degradation of Methylene Blue (MB) under visible light irradiation.
