In this study, novel zinc oxide-reduced graphene oxide (ZnO-RGO) nanorods have been fabricated on fluorine-doped tin oxide (FTO) glass substrate by the electrospinning process followed by a hydrothermal technique to grow supported nanorods. The ZnO-RGO precursor seed nanostructured layers were made by calcination of electrospinned nanofibers containing polyvinyl pyrrolidone, zinc acetate and different amounts of RGO at 400 °C for 1 h. Then they were used for hydrothermally growth (ZnO-RGO) Nanorods. The effect of amounts of RGO on the properties of ZnO-RGO NRs was investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectroscopy and Photoluminescence (PL). The obtained results evidenced that the coupling of RGO with ZnO improved the photocatalytic activity of ZnO. The ZnO-RGO nanostructure with 1.0 mL of RGO showed the highest photocatalytic activity through degradation of methyl orange (MO) under UV irradiation. © 2019
