Abstract
This study investigates the degradation of norfloxacin (NOF) using Ag3PO4/AgCl composite photocatalysts prepared via the in situ ion exchange method. The photocatalytic performance of the Ag3PO4/AgCl composite photocatalysts with different Ag3PO4 to AgCl ratios was estimated by the decomposition of NOF. The results indicated that the Ag3PO4/AgCl composite photocatalysts demonstrated enhanced photocatalytic activity and stability under visible light irradiation. This was attributed to the higher separation efficiency of photo-induced carriers in the composites, as indicated by photocurrent density and EIS measurements. Furthermore, the degradation process of NOF was investigated in detail through liquid chromatography-mass spectrometry analyses, revealing its mineralization behavior and decomposition pathways. Overall, these findings shed light on the potential application of Ag3PO4/AgCl composite photocatalysts for the effective degradation of NOF.
