The Ni/NiO nanocomposites were characterized with Fourier transformed infra-red spectroscopy (FT-IR), X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and X-Ray fluorescence (XRF). The XRD and XRF results confirmed that the nanocomposite products contain a mixture of nickel and nickel oxide. The Ni or NiO content vary with the temperature used for the synthesis. Upon increasing the temperature from 400 to 500C, the amount of NiO was found to be increase, due to a complete oxidation of Ni to NiO. The TEM images confiemed that the composites were spherical in shape with a distribution size of about 10-30 nm. In addition, the products display reasonable electrochemical performance. تفاصيل المقالة -
