N2 - ZnO nanorods combined with different concentrations of reduced graphene oxide were synthesized using the hydrothermal method. Structural properties of these nanocomposites were studied by X-ray diffraction analysis. Morphological studies on the shape and size of nanorods were carried out by scanning electron microscopy. X-ray diffraction results revealed highly-crystalline nanorods with a hexagonal wurtzite structure. The morphology of as prepared samples is characterized presence of one-dimensional rod-like nanostructures. Crystallite size, stress and lattice strain were determined by Scherrer equation and Williamson-Hall method. The average particle size of samples calculated from microstructural and morphological analyses are highly interrelated. Microraman spectra exhibited both characteristic bands of ZnO and reduced graphene oxide in the low frequency (300-500 cm-1) and high frequency (1300-1600 cm-1) ranges, respectively, furthermore confirming the efficiency of the hydrothermal synthesis of ZnO/reduced graphene oxide nanocomposites. The band gap of the nanocomposite is lower (2.96 eV).compared to that of ZnO (3.10 eV), as determined from the analysis of UV absorbance spectra.
