摘要
Visible-light-driven (VLD) BaFe12O19/BiOBr composite catalysts with different mass ratios of BaFe12O19 are prepared via hydrothermal and calcination method. The constructed S-type heterojunction enables BaFe12O19/BiOBr photocatalysts to perform effective space charge transfer and higher redox ability. Especially, the obtained BaFe12O19/BiOBr composites exhibited the high photocatalytic activity (95%) to degrade 2-mercaptobenzothiazole (MBT) only after 3 minutes of visible light irradiation, which was much better than pure BaFe12O19 (10.6%) and BiOBr (49%). What’s more, the BaFe12O19/BiOBr composites can be separated magnetically, thus achieving the practical significance of efficient separation and recovery. Photocatalytic activity experiments demonstrated that the prepared composites also showed good photocatalytic degradation performance towards Tetracycline hydrochloride (TC), Ciprofloxacin (CIP) and Eosin. Overall, the separable BaFe12O19/BiOBr composite photocatalysts will be promising candidate materials in sewage purification.
