/rGO (ZTG) was synthesized via hydrothermal technique. The X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) results substantiated the formation of ternary composites. From field emission-scanning electron microscope (FE-SEM) and high resolution-transmission electron microscope (HR-TEM) analysis, it was noticed that rGO sheets were wrapped tightly on the edges of both ZnO and TiO
