Abstract

Physical Characterization of Copper oxide nanorods synthesized by chemical precipitation via an alkaline reagent was achieved. X-ray diffraction analysis confirmed the nanocrystalline structure, and high-resolution TEM revealed the nanorod shape of the CuO particles. The lattice dynamic study revealed the formation of the oxide network, and the optical data demonstrated a narrow optical band gap of 1.46 eV. Regarding the photoluminescence analysis, CuO under study was detected to exhibit a band-to-band recombination model. The photo catalytic activity of synthesized CuO nanorods was examined using methylene blue dye under visible light and using different doses of CuO (1, 2, 3, and 4 g/L). After 180 min of irradiation, the degradation abruptly accelerated to 97% in the case of a 4 g/L photocatalyst dosage. There are more active sites on the photocatalyst's surface when the amount of photocatalyst increases. Consequently, a greater production of •OH radicals can contribute to the dye solution's actual deterioration.
