Herein, 7CN-Fe, a carbon nanotube-restricted catalyst derived from MIL-101 (Fe), was prepared via co-calcination of the typical MOF cage with melamine. This process enabled the formation of Fe single-atom catalysts (Fe-SACs) and optimized the exposure of active sites for boosted ciprofloxacin (CIP) degradation in a photoelectrocatalytic system (PEC). The series of reactive sites, including CN-Fe, C-Fe, and Fe<sub>3</sub>-C, contributed to the enhanced CIP degradation, with the kinetics of CN-Fe being 23.7-fold higher than those of MIL-101(Fe) (increasing from 0.0051 to 0.121<!-- --> <!-- -->min⁻¹). Electron spin resonance (ESR) and quenching tests revealed that •OH, •O<sub>2</sub><sup>-</sup>, h<sup>+</sup>, <sup>1</sup>O<sub>2</sub>, and high valent iron (Hv-Fe) are contributors to CIP degradation, and among them, •O<sub>2</sub><sup>-</sup> and <sup>1</sup>O<sub>2</sub> dominated the decomposition process. Density functional theory (DFT) analysis results manifested that the CN-Fe, C-Fe and Fe<sub>3</sub>-C sites promoted the O<sub>2</sub> adsorption and the O-O bond length had extended. Among them, the Fe<sub>3</sub>-C sites had the minimum O<sub>2</sub> adsorption energy (E<sub>ads</sub> = -2.12<!-- --> <!-- -->eV) and the O-O bond had the longest length (l<sub>O-O</sub> = 1.432<!-- --> <!-- -->Å) after activation. Based on the influence factors evaluation, cycling test, the degradation of various antibiotics, and the detection of iron ion leaching, the 7CN-Fe catalysts exhibited a promising application potential with the traits of wide adaptability and stable structure. This work provides a route for photoelectrocatalytic degradation system establishment by optimized MIL-101 (Fe) and singlet oxygen generation for efficient removal of organic contaminants.","PeriodicalId":344,"journal":{"name":"Journal of Alloys and Compounds","volume":"102 4 Pt 1 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143736885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
