Effective removal of antibiotics from aqueous solutions has emerged as a hot research topic in wastewater treatment. Photocatalytic degradation is one the most effective methods to reduce ecological damage and environmental pollution. In this work, novel photocatalyst consisting Z-type heterojunction Bi2S3/Bi4Ti3O12 (BS/BTO) with visible light responses was prepared by an situ growth method, obtained material used for tetracycline hydrochloride (TC). The best performing BS/BTO-2, which exhibited high photocatalytic activity. rates TC reached 97.9% within 40 min illumination. demonstrated stability reproducibility even after 5 cycles. Electron spin resonance (EPR) tests quenching experiments established that ·O2– h+ were main species responsible elimination TC. On basis theoretical calculations experimental data, possible mechanism been proposed. structure, effectively increases absorption range decreases compounding efficiency photogenerated electrons holes, principally performance BS/BTO. Additionally, liquid chromatography–mass spectrometry (LC-MS) utilized investigate formation reaction intermediates. nontoxicity solution verified cultivating wheat seeds. This work offers guidance bismuth-based photocatalysts field sustainable treatments.

Опубликована: Ноя. 29, 2024

In response to the urgent need for efficient degradation of emerging organic contaminants, this study has developed a novel catalytic system based on an original Fe-doped aerogel catalyst (FeCAS) and its carbonization-enhanced variant (FeCAS-400), designed improve activation performance peracetic acid (PAA). The FeCAS/PAA achieves remarkable 96.1% sulfamethoxazole (SMX) without external energy input, while FeCAS-400/PAA further elevates SMX removal rate 98.4% (kobs = 0.326 min−¹) demonstrates effectiveness across broad pH range 3–11. Theoretical calculations reveal that carbonization enhances electron transfer between iron–carbon substrates, which contributes improved performance. also exhibits versatility in removing wide prevalent contaminants proves effective real water matrices. This synergistic approach, combining aerogels with metal–carbon transfer, holds promise extension other advanced oxidation processes, contributing assurance quality safety sustainability.
