Empowering wastewater treatment with step scheme heterojunction ternary nanocomposites for photocatalytic degradation of nitrophenol

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Jan. 26, 2025

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.

Research on the influence of g-C3N4 microstructure changes on the efficiency of visible light photocatalytic degradation

Water Research X, Journal Year: 2025, Volume and Issue: 28, P. 100315 - 100315

Published: Feb. 8, 2025

The structural modulation of pristine graphitic carbon nitride poses a considerable challenge in the rational design catalysts for efficient degradation small organic pollutants under visible light. In this study, we combined first-principles calculations and structure-function relationship to predict high-performance catalyst. results reveal that CN-8 demonstrates remarkable degree electron-hole separation. Notably, shows exceptional efficiency towards rhodamine B, tetracycline, bisphenol A, fluralaner light irradiation. Specifically, rate constants are 11, 4, 12, 32 times higher, respectively, compared bulk g-C3N4. Through density functional theory investigations relationship, it is confirmed superior catalytic activity lies modifying amino position, which alters electron cloud distribution promotes separation photo-generated pairs. This study provides valuable insights development eco-friendly photocatalysts environmental remediation.
