| 英文摘要 | Microplastics (MPs) pose significant environmental and health risks, and conventional disposal methods often suffer from inefficiency and potential ecological harm. Photocatalytic degradation has emerged as a promising solution. However, traditional TiO2-based photocatalysts are limited by high electron-hole recombination rates, narrow visible light absorption, and poor reusability. In this study, we develop and optimize a Fe3O4@TiO2/Ag nanocomposite for the efficient degradation of polyethylene (PE) MPs with facile recovery. The synergistic integration of Fe3O4 and Ag with TiO2 enhances visible light absorption and mitigates charge carrier recombination. Notably, the Fe3O4@TiO2/Ag nanocomposite exhibits a degradation efficiency of 15.54%, outperforming Fe3O4@TiO2 (12.63%) and pristine TiO2 (1.15%). Moreover, the composite maintains its performance over five consecutive cycles, underscoring its durability. The degradation efficiency of Fe3O4@TiO2/Ag was further optimized using response surface methodology. Overall, the developed Fe3O4@TiO2/Ag nanocomposite exhibits excellent photocatalytic efficiency, magnetic recoverability, and long-term stability, highlighting its potential for practical applications in mitigating microplastic pollution. |
