新型0D/3D InVO4/ZnIn2S4异质结光催化降解抗生素性能及机制
Photocatalytic degradation performance and mechanism of antibiotics by novel 0D/3D InVO4/ZnIn2S4 heterojunction
摘要
Abstract
ZnIn2S4 has inherent defects limiting photocatalytic activity.InVO4 was introduced via hydrothermal synthesis,yielding an InVO4/ZnIn2S4 material with a 3D flower-like ZnIn2S4 core and 0D InVO4 quantum dots for efficient visible-light CIP(ciprofloxacin)degradation.Through characterization(XRD,SEM,UV-Vis,FTIR,PL,XPS)and photocatalytic performance evaluation,the effective construction of Z-scheme heterojunction was reveled.At a molar ratio of 0.2∶1,degradation rate of 20 mg/L CIP wastewater is achieved 90.01％within 60 min,outperforming single components by 22.8％.Radical trapping and mechanistic studies show reactive species contributions in the order of·O2-＞h+＞·OH,with the Z-scheme interface electric field enhancing carrier migration/separation and catalytic performance.The results offer an efficient,stable photocatalyst for antibiotic wastewater treatment,and also highlight the importance of heterojunction interface regulation.关键词
