Abstract: In this paper, we report on the preparation of momordica-like CuO nanostructures by the hydrothermal method using freshly
extracted egg white protein (ovalbumin) in an aqueous medium. These momordica-like CuO nanostructures were characterised by
X-ray diffraction (XRD) and field-emission scanning electron microscopy (FE-SEM). XRD patterns showed that these nanostructures
had a polycrystalline nature with a monoclinic structure. FE-SEM images indicated that the momordica-like CuO nanostructures
obtained at 180°C for 15 h were composed of CuO nanorods with a length of less than 100 nm and a width ranging from 30 nm
to 50 nm. Finally, a possible growth mechanism for the momordica-like CuO nanostructures is proposed and discussed.
Keywords: CuO – momordica – nanostructures – egg white – ovalbumin
