摘要：It is crucial to develop high-performance catalysts for the degradation of antibiotic pollutants. In this paper, we reported an inverse opal Mn-doped WO3 (IO Mn-WO3) catalyst to effectively activate peroxymonosulfate (PMS) for the degradation of levofloxacin (LVX) under visible light irradiation. The degradation efficiency of this novel photo-Fenton-like system could reach almost 100% for LVX. The catalyst showed good recyclability and stability within five cycles. In addition, the possible degradation pathways, the main reactive oxygen species and the degradation mechanism were systematically investigated in this work. O2- and 1O2 were identified as the main reactive oxygen species in the degradation system. Mn doping can initiate PMS activation and improve charge transfer efficiency, WO3 can promote the reduction of Mn species to make the reaction in the system occur continuously, an inverse opal structure can further enhance light absorption and increase the contact area between the catalyst and the pollutant. This work integrated the Fenton-like catalytic effect and the photocatalytic effect into the designed catalyst for PMS activation and antibiotic degradation, which developed a feasible strategy to improve the degradation performance of Mn-based materials for environmental remediation. In this paper, we reported an inverse opal Mn-doped WO3 (IO Mn-WO3) catalyst to effectively activate peroxymonosulfate (PMS) for the degradation of levofloxacin (LVX) under visible light irradiation.
