Abstract
The increasing occurrence of bisphenol A (BPA) in water sources raises significant environmental and health concerns, demanding efficient and sustainable remediation strategies. In this work, we investigate the photocatalytic degradation of BPA using silver metal clusters (Ag5) supported on anatase TiO2 under simulated solar irradiation. The deposition of Ag5 clusters significantly enhances visible-light absorption, promotes charge separation and improves photocatalytic performance, achieving an apparent rate constant (kobs) of 0.0142 min-1, corresponding to a ~43% improvement compared to bare TiO2. In addition, the Ag5@TiO2 catalyst exhibits higher photocatalytic activity, demonstrating the beneficial effect of Ag5 clusters incorporation. HPLC-MS analysis enabled the identification of intermediate degradation products. Compared to literature reports on modified TiO2-based photocatalysts, the present system demonstrates competitive performance even at significantly lower catalyst loadings. These results highlight the potential of Ag5@TiO2 photocatalysts as highly efficient alternatives for removing endocrine-disrupting compounds from water.
