Popis: A green method using biological dependable processes has been established for the synthesis of CuO nanoparticles. Synthesis of CuO nanoparticles were done using an environmental friendly method by taking aqueous solution of copper(II) sulfate and leaf extract of Ixoro coccinea. Characterization of the synthesized CuO nanoparticles was done using instruments such as UV-visible spectrophotometer, scanning electron microscopy, transmission electron microscopy, and Fourier-transform infrared spectroscopy. The existence of peaks obtained in FTIR confirms CuO nanoparticles. A visible change was observed in the solution prepared as it changed from light blue to light brown to dark brown once the extract was added to the copper sulfate solution. An average size of 300 nm was obtained during SEM analysis due to the formation of nanoparticle clusters. The TEM images of CuO nanoparticles separated after ultrasonication of the dispersion show that they possess an average size of 80–110 nm. It was found that the ultrasonication increases the distribution of nanoparticles in a fluid by preventing the formation of clusters. It was found that Ixiro coccinea plant leaves are a suitable alternative for the easy and green synthesis of CuO nanoparticles.
