Optimization of Visible-Light-Driven Ciprofloxacin Degradation Using a Z-Scheme Semiconductor MgFeO/UiO-67.

A heterogeneous photocatalyst, MgFeO/UiO-67 (MU-), was successfully synthesized by doping magnetic magnesium ferrite nanoparticles (MgFeO) with the UiO-67 metal-organic framework at various weight ratios (MgFeO: UiO-67 at 30, 50, 70, and 90 wt %). Various techniques, including X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), Fourier transform infrared spectroscopy (FT-IR) , Brunauer-Emmett-Teller (BET), photoluminescence (PL), vibrating sample magnetometry (VSM), electrochemical impedance spectroscopy (EIS), and ultraviolet-visible diffuse reflectance spectroscopy (UV-vis DRS), were used to characterize the prepared photocatalysts. The photocatalytic performance of MU- in the degradation of ciprofloxacin (CIP) under visible light was assessed.
