Fe-doped ZnO (Fe:ZnO) was combined with both magnetite (Fe3O4) and carbonous materials (graphene) using a co-precipitation method to form Fe:ZnO/G/Fe3O4 nanocomposites with various weight ratios (1:0, 1:0.05, 1:0.1, 1:0.3, 1:0.5, and 1:1). These nanocomposites were characterized using different methods of measurements; such as Fourier transform infrared spectroscopy to record the absorption spectra of certain functional groups, X-ray diffraction spectroscopy to identify the structure of the samples, and thermogravimetric analysis to study the loss in samples' weight under increasing temperature. The magnetite and carbonous materials were used to support Fe:ZnO in the photodegradation of methylene blue dye, as a representation of organic dyes. The photocatalytic activity was examined under ultra violet (UV) light irradiation. The effects of Fe:ZnO/G:Fe3O4 ratio, scavenger addition, and catalyst dosage on the photocatalytic activity were also studied. Finally, the reusability of the catalyst was examined and proved.
