This study introduces a perylene diimide (PDI) small molecule in the photocatalytic degradation of antibiotics for first time. Initially, we optimized its photoelectric performance through self-assembly to obtain an n-type photocatalyst (SA-PDI). Subsequently, WO3 and Cu2O were incorporated using facile one-step method prepare n-n type n-p organic-inorganic hybrid photocatalysts (PDI-WO3 PDI-Cu2O). approach simultaneously achieved self-assembly, metal ion doping, inorganic hybridization, further modulating properties materials. Studies indicated that PDI-WO3 operates via type-II heterojunction mechanism, whereas PDI-Cu2O follows S-scheme mechanism. SA-PDI demonstrated superior efficiency toward tetracycline hydrochloride (TCH), while exhibited enhanced activity both TCH doxycycline (DOX). In contrast, showed higher efficacy ciprofloxacin (CIP) norfloxacin (NOF). These differences are attributed distinct active species generated by each catalyst, aligning with requirements specific antibiotics. Moreover, since all three materials based on PDI molecule, they inherently compatible. Consequently, directly mixed these composite simultaneous multiple simulated wastewater system, systematically investigated effects ions, humic acid, pH effectiveness treating antibiotic solutions. Ultimately, this provides novel design strategies demonstrates promising potential practical applications mitigating contamination real systems.

Adsorption and Photodegradation of Organic Compounds in Wastewater by Hierarchical Organic Molecular Sieves

ChemistrySelect, Journal Year: 2025, Volume and Issue: 10(5)

Published: Feb. 1, 2025

Abstract Dyes with aromatic structures are known for their persistence and high toxicity. Once these dyes enter aquatic environments, they pose significant threats to both the ecosystem human health. In this study, N,N ‐dimethylethylenediamine(DMEN) was used as a template synthesize ZIF‐8 material, characterized by specific surface area mesoporosity. The hierarchical material is utilized remove from simulated wastewater. It can adsorb organic dye molecules harmful metal ions dye‐laden And two processes do not exhibit interference each other. results indicate that exhibits excellent adaptability wastewater environments salinity extreme pH levels. equilibrium adsorption capacity of methylene blue twice microporous ZIF‐8, its photocatalytic efficiency enhanced 30% compared ZIF‐8. Moreover, performance significantly improves under alkaline conditions: at 12, degradation rate reaches 96.9%. study found primarily follows reaction mechanism during catalytic blue. Hierarchical demonstrates potential application in textile treatment.
