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.
