TLDR
Using a simple wet-chemical route, the authors synthesized CuO nanorods with diameters of ca. 5-15 nm and lengths of up to 400 nm, and the purity, crystallinity, morphology, structure features, and chemical composition of the as-prepared CuO nano-objects were investigated by powder X-ray diffraction, transmission electron microscopy, high-resolution transmission electron microscope, Xray photoelectron spectroscopy, and Raman spectroscope.Abstract:
