摘要

In2S3具有优异的光催化性能，包括高载流子迁移率和强光吸收，提高了太阳能转换效率。本研究制备了含20wt .%、30wt .%和40wt .% In2S3的活性炭（AC）衍生光催化剂，考察其与过硫酸氢盐（PDS）降解环丙沙星（CPX）的性能。还评价了pH（2.5-8.5）的影响。采用XRD、FE-SEM、BET、UV-Vis、光电流、PL、ERS和Mott-schottky分析对掺量为30wt .% In2S3的复合材料进行了表征。PDS将CPX的光降解性能从60.8%提高到99.7%。CPX降解的最佳条件为pH = 5.5。此外，清除试验强调了超氧化物（•O2-）、羟基（•OH）、硫酸盐（•SO4毒血症）和电子（e-毒血症）在CPX光降解过程中的显著作用。

Intensified wastewater treatment using In2S3 on activated carbon derived from waste tire: Peroxydisulfate activation via visible-light, characterization, composition, pH influence, and mechanism

In₂S₃ exhibits exceptional photocatalytic properties, including high charge carrier mobility and strong light absorption, enhancing its efficiency in solar energy conversion. In this study, activated carbon (AC) derived photocatalyst with 20, 30, and 40 wt.% of In₂S₃ was prepared in order to investigate its performance with peroxydisulfate (PDS) in ciprofloxacin (CPX) degradation. The effect of the pH (2.5–8.5) was also evaluated. The composite with 30 wt.% In₂S₃ in the presence of PDS showed the best performance, and characterized by XRD, FE-SEM, BET, UV–Vis, Photocurrent, PL, ERS, and Mott-schottky analyses. PDS enhanced the performance of photodegradation of CPX from 60.8% to 99.7%. The optimal conditions for CPX degradation were determined to be at a pH of 5.5. Additionally, scavenging tests highlighted the notable role of superoxide (^•O₂^-), hydroxyl (^•OH), sulfate (^•SO₄^⁻), and electrons (e^-) in the photodegradation process of CPX.
