“…SDS could facilitate the growth of loos flower-like structures by organizing nanosheets with a higher surface lattice exposure, resulting in the superior photocatalytic degradation of pharmaceutical complex organic pollutants like tetracycline (TC) and ciprofloxacin (CIP). 22 Its spherical structure provides the maximum surface area with more oxygen defects than a flower-like morphology. 3D photocatalysts favor photocatalytic reactions due to their more active sites, ability to harvest the maximum light energy, and as their quick dispersion can accelerate the migration of exciton pairs.…”

“…The preparation of MgFe 2 O 4 / UiO-67 was performed following the reported procedure with some modifications. The weight of MgFe 2 O 4 was calculated as the percentage of UiO-67 (10,30,50,70, and 90 wt %), which is equivalent to 0.037, 0.112, 0.187, 0.261, and 0.336 g, respectively. In brief, a certain amount of MgFe 2 O 4 was dispersed in 25 mL of DMF and ultrasonicated for 30 min.…”

A heterogeneous photocatalyst, MgFe 2 O 4 /UiO-67 (MU-x), was successfully synthesized by doping magnetic magnesium ferrite nanoparticles (MgFe 2 O 4 ) with the UiO-67 metal−organic framework at various weight ratios (MgFe 2 O 4 : UiO-67 at 30, 50, 70, and 90 wt %). Various techniques, including Xray 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-x in the degradation of ciprofloxacin (CIP) under visible light was assessed. The CIP degradation efficiency was found to increase as the amount of MgFe 2 O 4 in the composite was increased up to 70 wt %. Experimental conditions were optimized using response surface methodology (RSM) based on central composite design (CCD) with three factors: initial pH, catalyst loading, and CIP concentration. Using the obtained model, the optimal conditions were determined as follows: initial pH of 8.025, catalyst loading of 33.8 wt %, and CIP concentration of 10.8 mg/L. Under these optimal conditions, a notable improvement was achieved, with 99.62% of CIP removal achieved within 90 min, surpassing the performance of previously reported photocatalysts. Total organic carbon (TOC) analysis revealed a high degree of mineralization, at 81.25%. The degradation pathway of CIP was investigated based on liquid chromatography−mass spectrometry (LC-MS) analysis. Finally, the values of E CB and E VB of the photocatalyst were determined and the possible degradation mechanism of CIP was investigated based on Mott−Schottky and the applied scavengers. The hydroxyl radical ( • OH) was identified as the dominant species in the removal of CIP through a trapping experiment. The photocatalyst with 70 wt % of MgFe 2 O 4 (MU-70) exhibited excellent stability and recoverability with an external magnet, demonstrating 86.33% CIP removal after four cycles. According to the obtained results, MU-70 is a promising visible-light-active photocatalyst with great potential for water treatment applications and convenient recovery.

Tetracycline (TC) adsorption amount on original wood biochar was finitely, so modification is imperative to improve its adsorption capacity. This study mixed chinese fir sawdust with ammonium molybdate to prepare a modified chinese fir biochar (MCB) via pyrolysis at 800 °C. Meanwhile, pristine chinese fir biochar (CB) was produced as control. The effects of pH, adsorption time, initial concentration and adsorbent dosage on the adsorption process were also studied. Langmuir model and quasi second-order kinetic model were used describe the characteristics of adsorption process. The optimally capacity of TC adsorption on MCB reached 36 mg/g, which was 6 – fold increase to CB. Therefore, modification by ammonium molybdate can be used as a potential way of chinese fir sawdust biochar for increasing adsorption capacity of TC from antibiotic sewage water.
