| 英文摘要 | Quinolones are widely used in the pharmaceutical industry; however, the high residue of these antibiotics has caused serious water quality issues, and their effective removal is still a great challenge. In this work, bimetallic magnetic FexMny catalysts are prepared by a facile impregnation method and are efficient for photocatalytic removal of five typical quinolone pollutants without oxidant under simulated light irradiation. The fabricated bimetallic magnetic FexMny catalyst with the Fe3+/Mn2+ ratio of 1 : 1 exhibits a large surface area of 122.5 m(2) g(-1), highly porous structure, rich defects and a covalent metal environment. These fabricated semiconductor catalysts can degrade 98.3% of ciprofloxacin (CIP), 96.0% of ofloxacin (OFL), 91.0% of enrofloxacin (ENR), 92.2% of levofloxacin (LEV), and 93.5% of norfloxacin (NOR) in 30 min without using any oxidant. The magnetic FexMny catalysts can be simply recycled using a magnet and maintain high stability, avoiding complex recycling procedures. Even after five cycles, the degradation rate of CIP was still over 92.0%. The degradation performance is far superior to that of most previously reported candidates. The bimetallic FexMny catalyst improves the ability to capture sunlight, increases the interface charge transfer rate, and inhibits the recombination of photogenerated electron-hole pairs. In addition, the mechanism and the main intermediates in the photocatalytic degradation of CIP are explored by quenching experiments, electron paramagnetic resonance (EPR) and liquid chromatography-mass spectrometry (LC-MS) analysis. These noble-metal free magnetic FexMny catalysts provide a promising opportunity for advanced photocatalytic oxidation technology to treat wastewater. |
