Synthesis and Characterization of Rice-Grain-Shaped Nanostructured Copper Oxide by a Chemical Method

Rahul Yadav, R. R. Attarde

Abstract: The work presented in this article aims to synthesize nanostructured copper oxide (CuO). The nanostructured copper oxide was synthesized by a chemical method, specifically the simple, low-cost co-precipitation method. The objectives of the present work are to synthesize and characterize nanostructured copper oxide using copper nitrate as the precursor. The synthesized nanostructured copper oxide samples were characterized by various methods, such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), ultraviolet-visible (UV-Vis) spectroscopy, and field emission scanning electron microscopy (FESEM) with energy dispersive X-ray spectroscopy (EDS). The XRD and FTIR results confirm the pure form of copper oxide. The crystallite size observed is approximately 15-19 nm, according to the XRD results. The UV-Vis results show absorption peaks below ~450 nm, which also confirms the formation of copper oxide with a band gap of approximately 2.75 - 3 eV. FESEM images reveal a rice-shaped morphology. EDS results reveal the elemental composition of the CuO sample.
