This study aimed to investigate the photocatalytic performance of diverse zinc oxide catalysts containing gold nanoparticles (AuNPs), molybdenum disulfide (MoS2), and reduced graphene (rGO) toward degradation antibiotics levofloxacin (LFX) ciprofloxacin (CFX) in aqueous solutions. The obtained results demonstrate that LFX is more resistant when compared with CFX principal route under visible light formation hydroxyl radicals. Photoluminescence (PL) measurements were employed verify inhibitory effect electron–hole recombination AuNPs, MoS2, rGO are integrated into a semiconductor. catalyst achieved highest percentage was 1%Au@ZnONPs-3%MoS2-1%rGO, exhibiting efficiency 96%, while exhibited 5%Au@ZnONPs-3%MoS2-1%rGO, displaying 99.8%. A gas chromatography–mass spectrometry (GC-MS) analysis enabled identification reaction intermediates, facilitating determination potential pathway for both antibiotics. Additionally, recyclability assessments showed synthesized maintained stable efficiencies after 15 cycles, indicating heterostructures have further usage may be tested other organic contaminants as well.

Chemistry - A European Journal, Год журнала: 2024, Номер 30(37)

Опубликована: Апрель 30, 2024

Abstract Main group Bi‐based materials have gained popularity as N 2 reduction reaction (NRR) photo/electrocatalysts due to their ability inhibit competitive H evolution reactions (HER) and the unique adsorption activities. The introduction of defects in catalysts represents a highly effective strategy for enhancing light absorption, promoting efficient separation photogenerated carriers, optimizing activity free radicals, regulating electronic structure, improving catalytic performance. In this review, we outline various applications state defect engineering elucidate impact vacancies on NRR particular, types defects, methods tailoring, advanced characterization techniques, well with abundant corresponding behavior were elucidated detail. Finally, main challenges opportunities future development defective are discussed, which provides comprehensive theoretical guidance field.
