Fabrication of magnetic BaFe12O19/Ag3PO4 composites with in situ photo-Fenton-like reaction for enhancing reactive oxygen species under visible light irradiation

Abstract

This research was designed to synthesize a magnetic in-situ Fenton-like photocatalyst using simple methods. The sheet materials of BaFe12O19, inherent magnetic properties, decorate Ag3PO4 and in-situ catalytic conversion of the H2O2 that generated on the surface of Ag3PO4 could produce more reactive oxygen species (ROS) for degradation organic pollutants via a photo-Fenton process. ESR, trapping experiments of different scavengers and H2O2 detection proved that the ROS of oxidation of bisphenol A (BPA) is mainly produced by the Fenton-like reaction. This work has effectively improved the degradation activity of Ag3PO4. Simultaneously, the BaFe12O19/Ag3PO4 composite can be easily separated from the reaction system via applying an external magnetic field, which shows a promising application for the photo-oxidative degradation of environmental contaminants.
