Abstract

 

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 CuX2 ⋅n H2O, ZnX2 ⋅n H2O (X = Cl–, NO3, 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.
