Abstract

We report a novel method that allows the synthesis of copper oxide (CuO) nanostructures and control their morphology and size by rapid thermal decomposition of copper nitrate (CuN₂O₆) under ambient conditions. The size and morphology of the nanostructures can be controlled by changing the temperature and the duration of the decomposition process. The structure of the products was investigated by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) equipped with energy dispersive spectroscopy (EDS). The results showed that the morphology of the nanostructures changed as the temperature was varied and their size increased with increasing the treatment time. The optical properties of the samples were investigated by UV-vis spectroscopy and a photoluminescence (PL) spectrometer. Rice-like nanostructures were observed and analyzed by X-ray photoelectron spectroscopy (XPS)/EDS and XRD which confirmed that the as-synthesized powders correspond to pure CuO.
