Abstract
The increasing frequency of pharmaceutical pollutants in water sources poses significant environmental and health challenges worldwide. Among these, moxifloxacin antibiotic persists in aquatic environments, exerting adverse effects on ecosystems and human health. In this study, we synthesized BiFeO3@ZIF-67 nanocomposites through the "bottle around ship" method and investigated their efficacy as co-catalysts for the photodegradation of moxifloxacin. Characterization techniques including X-ray diffraction (XRD) and scanning electron microscopy (SEM) confirmed the successful encapsulation of BiFeO3 nanoparticles within the ZIF-67 framework. Photocatalytic experiments demonstrated a significant enhancement in moxifloxacin degradation efficiency using BiFeO3@ZIF-67 nanocomposites compared to pristine BiFeO3 and ZIF-67 nanoparticles. The optimized nanocomposite exhibited a removal efficiency of up to 87 % under solar irradiation within 90 min. The synergistic effects between BiFeO3 nanoparticles and ZIF-67 matrix contribute to improved light absorption and generation of reactive oxygen species, facilitating the degradation of moxifloxacin. Our findings highlight the potential of BiFeO3@ZIF-67 nanocomposites as sustainable and efficient co-catalysts for the remediation of antibiotic-contaminated water sources, addressing critical environmental and public health concerns.
