Copper oxide nanoparticles (CuONPs) have been classified as an important metal oxide semiconductors with the special physical and chemical characteristics. CuONPs can be able to synthesize through different methods and techniques, such as sonochemical, precipitation, sol-gel, chemical bath deposition, hydrothermal approach, chemical reduction as well as reflux contestation. In this work, CuONPs were synthesized by a cost-effective, green and simple procedure using rosmarious officinalis extract at room temperature. These NPs were fully characterized by field-emission scanning electron microscopy (FESEM), Fourier transform infrared spectroscopy (FT-IR), UV-vis absorption and X-ray diffraction (XRD). These nanoparticles were applied in click chemistry and had an applicable and tunable results. [1-3]
