摘要

Bismuth Sulfide (Bi₂S₃) nanoparticles were synthesized using the hydrothermal method. Their elemental composition was confirmed through energy dispersive X-ray spectroscopy (EDX). The morphology of the nanoparticles was analyzed using field emission scanning electron microscopy (FESEM) and high-resolution transmission electron microscopy (HRTEM). X-ray diffraction (XRD) analysis confirmed the orthorhombic crystal structure of the Bi₂S₃ nanoparticles. The average crystallite size and lattice strain were determined using the Debye–Scherrer formula, yielding values of approximately 55.60 nm, 7.8 × 10⁻4 and a dislocation density of 5.61 × 1014 lines/m2. X-ray Photoelectron Spectroscopy (XPS) analysis confirmed the binding states of Bi₂S₃ nanoparticles, validating their oxidation states and chemical bonding characteristics. Thermogravimetric analysis (TGA) revealed a two-stage decomposition process, which was used to calculate kinetic parameters related to the thermal stability of the nanoparticles. The zeta potential was measured at -19.1 mV, suggesting good stability and resistance to agglomeration. The optical band gap was found to be 1.32 eV. Photocatalytic efficiency was evaluated based on the Langmuir–Hinshelwood kinetic model, from which the rate constants k₁ and k₂ were determined for a nanoparticle concentration of 0.5 g/L. Furthermore, the study explored the potential applications of Bi₂S₃ nanoparticles in pressure sensing and infrared detection technologies.
