ABSTRACT The inability to recycle Fenton reagents and a narrow pH range restricts hematite (Fe 2 O 3 ) application in the actual photo‐Fenton system. engineering of surface structures is identified as an effective approach for enhancing activity material. In this work, three different morphologies (nanosheet, cube, ring) Fe materials containing oxygen vacancies (OVs) were synthesized by hydrothermal method, novel system degradation sulfamethazine was examined. presence oxalic acid, /oxalic acid heterogeneous catalytic demonstrated situ generation H facilitated Fenton‐like reactions. as‐prepared nanosheet‐Fe showed highest efficiency. free radical capture experiment investigated using sacrificial agents, results suggested that superoxide radicals principal active species involved. Ecotoxicity assessments utilizing toxicity prediction software assessed reaction intermediates generated during via quantitative structure–activity relationship indicating these exhibited reduced developmental toxicity. possible pathways mechanism synergistic effect between proposed. This research presents strategy design synthesis photocatalysts with various vacancies, suitable catalysis related environmental contexts.

Ag2S/Zn2+-Decorated g-C3N4 Type-II Heterojunction with Wide-Spectrum Response: Construction and Photocatalytic Performance in Ciprofloxacin Degradation

Molecules, Год журнала: 2025, Номер 30(7), С. 1417 - 1417

Опубликована: Март 22, 2025

Antibiotic-based wastewaters seriously endanger human health and damage the ecological environment, photocatalytic degradation is a desirable strategy for eliminating these contaminants in water. Therefore, developing proper catalyst photodegradation of antibiotics, including ciprofloxacin (CIP), great importance. In this study, novel Ag2S/Zn2+-decorated graphitic carbon nitride (AZCN short) type-II heterojunctions are constructed through precipitation–calcination procedure. The high porosity with specific surface area 133.5 m2 g−1, as well positive synergy between Ag2S- Zn2+-decorated (abbreviated ZCN), enhance incident light harvesting, increase adsorption capacity reactant molecules, favor mass transfer promote separation transport photoinduced carriers, therefore improving efficiency CIP. Specifically, CIP (50 mL, 10 mg L−1) over 2.5% AZCN (10 mg) 18.1%, 43.1% 55.7% within 60 min irradiation using near-infrared light, visible simulated solar respectively. Moreover, it displays satisfactory recycling stability excellent universality. This research not only develops promising heterojunction photocatalyst but also offers some valuable insights water remediation.
