A series of reduced graphene oxide (rGO) supported zirconia (ZrO2) nanocomposites with 1, 2 and 5 wt.% GO were synthesized using the sol–gel technique. The reduced graphene oxide/zirconia composites were characterized by X-ray powder diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM) high resolution transmission electron microscopy (HRTEM), ultravioletvisible (UV–Vis) and, X-ray photoelectron spectroscopy (XPS), and N2 adsorption and desorption ...
