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.

Π‐Bridge Modulations in D–π–A Conjugated Microporous Polymers to Facilitate Charge Separation and Transfer Kinetics for Efficient Photocatalysis

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(44)

Published: May 16, 2024

Abstract The burgeoning field of conjugated microporous polymers (CMPs) has generated widespread interest due to their potential as photocatalysts for hydrogen production from water. Nevertheless, photocatalytic performance is sometimes hindered by inadequate charge separation and transfer, coupled with rapid recombination. Herein, a strategy enhance via the customization π ‐bridges through modulation heteroatoms in series donor‐ ‐acceptor (D‐ ‐A) CMPs proposed. This affords optimized energy levels improved thus boosting efficiency. Among various heteroatom substitutions, S‐doped CMP (10 mg) demonstrates highest evolution rate 203 µmol h −1 (AQY 450nm = 7.4%) under visible light irradiation. Subsequent experimental analysis reveals its superior can be largely related minimized exciton binding energy, facilitated transfer efficiency, impeded recombination among these heteroatom‐doped D‐ ‐A CMPs. research paves way rational design modification organic semiconductors advanced solar‐driven photocatalysis promoting transfer.
