Influence of synthesis conditions on particle morphology of nanosized Cu/ZnO powder by polyol method
Tuba Gürkaynak Altinçekiç Ismail Boz
Cu/ZnO in nanosizes have been synthesized using ethylene glycol at various conditions. The effects of reaction temperature, extent of reduction, various precursors such as CuX$_{2}.n$H2O, ZnX$_{2}.n$H2O (X = Cl–, NO$^{–}_{3}$, CH3CO$^{–}_{2}$), the addition of water and the removal of volatile compounds including water were studied by X-ray diffraction (XRD), scanning electron microscopy (SEM), and dynamic light scattering (DLS). Cu/ZnO powders with an average diameter of as low as 50 nm was obtained with a very low polydispersity in the absence of a protective polymer. Ethylene glycol oxidation products were also identified by Fourier transform infrared (FTIR) spectroscopy. The morphology of Cu/ZnO powders and the yield of powders are found to be strongly dependent on the synthesis conditions.
