In this present work, the effects of coating of graphene oxide (GO) at different concentrations (0, 0.2, 0.3, 0.4, 0.5, and 0.6 mg/ml) onto zinc oxide (ZnO) nanostructured were investigated. ZnO and ZnO coated with GO (ZnO/GO) were prepared using immersion method. The structural, morphology and optical properties of all samples have been studied using x-ray diffraction (XRD), field emission scanning microscopy (FESEM) and UV Vis spectroscopy. The peak obtained from the XRD pattern shows that all samples are in the hexagonal-wurtzite structure. The (002) peak shows the strongest intensity for all samples with the highest (002) peak obtained for the ZnO/GO sample coated at a GO concentration of 0.5 mg/ml. The diameter of ZnO/GO nanostructured samples decreased after coating with GO at concentrations of 0.2 to 0.5 mg/ml and the diameter increased again when ZnO nanostructures were coated with GO at above 0.5 mg/ml. The highest transmission spectrum was obtained for the ZnO/GO sample coated with GO at a concentration of 0.5 mg/ml. In conclusion, the effect of GO coating on ZnO nanostructured can be changed at different concentrations of GO. The optimal properties of ZnO/GO may be suitable as a photoanode in DSSC applications © 2022, Journal of Advanced Research in Fluid Mechanics and Thermal Sciences.All Rights Reserved.
