Enhancing photocatalytic performance of Fe3O4 nanoparticles and Fe3O4@ZnO nanocomposites

In this work, Fe3O4 nanoparticles and Fe3O4@ZnO nanocomposites were prepared by co-precipitation and reflux techniques, respectively. Structural, magnetic, and photocatalytic properties were studied. The crystalline structure and morphology were confirmed by X-ray diffraction (XRD) and high-resoluti...
