The ongoing challenge of water pollution necessitates innovative approaches to remove organic contaminants from wastewater. In this work, new two-dimensional S-scheme heterojunction photocatalysts Bi2O3/CdS and MoS2/Bi2O3/CdS that are intended for the effective photocatalytic destruction 4-nitrophenol, a dangerous pollutant, synthesized characterized. Utilizing solvothermal method, successfully generated these ternary nanocomposites, which were characterized through various techniques including X-ray diffraction (XRD), scanning electron microscopy (SEM), photoelectron spectroscopy (XPS), high resolution transmission electronmicroscopy (HRTEM), Brunauer-Emmett-Telle (BET) diffuse reflectance (DRS). Our results demonstrated achieved an 86% degradation rate while composite exhibited exceptional performance, achieving nearly complete (99%) within 120 min under visible light irradiation. Most importantly improved activity originated release internal electric field in heterojunction. This enhanced is attributable synergistic effects heterojunctions facilitate more charge separation generation with OP RP confirmed synthesis using S-scheme. further by XPS, DRS, XPS-VB photocurrent response. These findings highlight promising application advanced real-world wastewater treatment processes, offering sustainable solution combat pollution.

During the process of producing potassium fertilizer from salt lake resources, a large amount waste liquid brine, rich in raw materials such as magnesium chloride, is generated. In this work, MoS2/MgAl-LDH composite material was constructed using secondary hydrothermal technique. Characterizations including X-ray diffractometer (XRD), scanning electron microscopy (SEM), and photoelectron spectroscopy (XPS) confirmed distribution MoS2 nanosheets on surface MgAl-LDH. Under full-spectrum irradiation, degradation efficiency Rhodamine B reached 85.5%, which 69.2% higher than that MgAl-LDH alone. The results electrochemical, UV-Vis, XPS-VB tests indicate internal electric field accelerated separation transportation charge carriers between These findings demonstrate great potential photocatalyst organic dyes, will aid green recycling utilization resources by-products.

Abstract Photocatalytic degradation using freely available sun light is one of the crucial approaches in remediation persistent organic pollutants, such as rhodamine B (RhB). Developing effective photocatalysts key challenges meeting sustainable development goals. In this study, a series binary composite bismuth oxybromide (BiOBr) with varying amounts polyaniline (PANI) were synthesized at room temperature. The nanocomposite, 9 wt % PANI (PB‐70) displayed enhanced photocatalytic performance for RhB dye when compared to bare and BiOBr, under visible light. 20 ppm reached 100% about 30 min PB‐70 photocatalyst. Moreover, complete mineralization also could be achieved PB‐70. Predominant involvement superoxide ion (•O 2 ─ ) radicals along lower contributions from holes (h + hydroxyl (•OH) was evident scavenger studies. Enhanced photophysical properties confirmed, BiOBr. Formation Z ‐scheme heterojunction between BiOBr thus, found reason activity.
