UV-Irradiated Photocatalytic Activity of α-Fe2O3/ZnO Nanocomposites for Wastewater Treatment
This work demonstrates the successful synthesis of pure α -Fe 2 O 3 , pure ZnO, and α -Fe 2 O 3 /ZnO nanocomposites with weight ratios of 1:1, 1:2, 1:3, and 1:4 by an efficient hydrothermal method for wastewater treatment. The structural, morphological, optical, and magnetic properties of the synthe...

/ZnO nanocomposites with weight ratios of 1:1, 1:2, 1:3, and 1:4 by an efficient hydrothermal method for wastewater treatment. The structural, morphological, optical, and magnetic properties of the synthesized samples were characterized by x-ray diffraction (XRD), high-resolution transmission electron microscopy (HR-TEM), ultraviolet–visible (UV–Vis) spectroscopy, and vibrating-sample magnetometry (VSM), respectively. The XRD pattern confirmed the successful formation of the synthesized samples. Particle size in the range of 30–36 nm was calculated for the nanocomposite using HR-TEM. UV–Vis spectroscopy was used to calculate the optical bandgap of the synthesized nanocomposites, which varied from 1.96 eV (FZ11) to 2.27 eV (FZ14). This difference was explained by the introduction of ZnO, which is a wide-bandgap semiconductor. The value of magnetization decreased from 0.37 emu/g to 0.04 emu/g as the content of ZnO increased.
