The Electronic Structure of Sb2S3 Wire and Its Application in Visible-Light-Driven Photodegradation of Methylene Blue
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.
期刊介绍：
Protection of Metals and Physical Chemistry of Surfaces is an international peer reviewed journal that publishes articles covering all aspects of the physical chemistry of materials and interfaces in various environments. The journal covers all related problems of modern physical chemistry and materials science, including: physicochemical processes at interfaces; adsorption phenomena; complexing from molecular and supramolecular structures at the interfaces to new substances, materials and coatings; nanoscale and nanostructured materials and coatings, composed and dispersed materials; physicochemical problems of corrosion, degradation and protection; investigation methods for surface and interface systems, processes, structures, materials and coatings. No principe restrictions exist related systems, types of processes, methods of control and study. The journal welcomes conceptual, theoretical, experimental, methodological, instrumental, environmental, and all other possible studies.
