“…Bismuth sulfide (Bi 2 S 3 ) has gained serendipitous popularity as a semiconducting material for photocatalysis due to its exceptional electrical and optical properties, such as a relatively narrow band gap (1.3-1.9 eV), high absorption coefficient, good visible light harvesting, and low toxicity [13,14]. However, its photocatalytic application has been limited mainly due to the significant charge carrier recombination rate and photo corrosion.…”

A visible-light-active plasmonic photocatalyst was prepared from bismuth sulfide particles modified with Ag-AgCl nanoparticles. The structure of the photocatalyst was analyzed using powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), elemental mapping, nitrogen adsorption-desorption isotherms (BET-BJH), and diffuse reflectance spectroscopy (DRS). To evaluate the photocatalytic performance, Acid Blue 92 (AB92) azo dye was degraded in an aqueous solution under visible light illumination. It was found that 0.025 g of the photocatalyst was able to remove over 98% of the AB92 solution at a concentration of 15 ppm and pH 7.5, in accordance with pseudo-first-order kinetics. Superoxide anion radicals (O2-˙) are key components of the photodegradation pathway. Furthermore, the antibacterial activity of the material was investigated against E. coli and S. aureus under irradiation and dark conditions. Transmission electron microscopy (TEM) images of the treated cells showed that the plasmonic photocatalyst destroyed the gram-positive and gram-negative bacterial cell wall structures within two hours of treatment. It is possible that this was caused by efficient generation of destructive superoxide anion radicals on the surface of Ag-AgCl/Bi2S3 particles.

“…Jia et al [23] utilized a CTAB-assisted hydrothermal synthesis route to obtain 3D Bi2S3 for photocatalytic degradation of RhB. However, for the above-mentioned methods for synthesizing Bi2S3, complex and expensive equipment is generally required, or additional surfactants, ligands, or toxic organic solvents are needed [20][21][22][23][24][25][26], which are not environmentally friendly. Furthermore, most studies have focused on a single morphology of Bi2S3, and the research on the 1D/2D Bi2S3 is relatively limited, indicating the need for further exploration.…”

The crystal structure and morphology of photocatalysts play a crucial role in determining their photocatalytic performance. In this study, we synthesized and investigated 1D/2D Bi2S3 as a potential visible-light-activated photocatalyst for the reduction of aqueous Cr(VI). The 1D/2D Bi2S3 was synthesized using hydrothermal synthesis technique by heating Bi2(H2O)2(SO4)2(OH)2 precursor and sodium sulfide at 190 ℃ for 24 h, where the molar ratio of Bi to S elements in the reaction reagents was changed from 1:6 to 2:3. The structure, composition, and optoelectronic properties of the prepared Bi2S3 were characterized using X-ray diffraction, UV-vis diffuse reflectance spectra, field emission scanning electron microscopy, electrochemical impedance spectra, and transient photocurrent. It is shown that the prepared orthorhombic Bi2S3 has full-spectrum photoresponsivity. Bi2S3-B with 1D/2D heterogeneous structure exhibits the lowest charge carrier transport resistance, and its photocurrent intensity is nearly twice that of Bi2S3-C. It demonstrates the highest photocatalytic activity in visible-light photocatalytic reduction of aqueous Cr(VI), with a reduction rate of 54.5% after 140 minutes of light exposure. According to the bandgap of Bi2S3 and radical scavenger experiments, a reaction mechanism for the photocatalytic reduction of Cr(VI) by Bi2S3 was proposed. Furthermore, the results highlight the economic and environmentally friendly nature of the hydrothermal synthesis method using homemade precursors, which allows for the regulation of Bi2S3 morphology and the enhancement of its visible photocatalytic activity.
