Today, the green synthesis of metal oxide nanoparticles has received increasing attention due to the development of eco-friendly technologies in materials science. In this work we aim that could produce two nano metal oxide of Co2+ and Cu2+ ions using simple method in starch media as a natural polymer via sol-gel method successfully. The aqueous solution of cobalt and copper ions were added dropwise to the solution of starch and glucose. The obtained precursors were calcined at 500°C temperatures under air for 2h. The produced nanoparticles were characterized by XRD analyses and SEM images. Also, some different applications of cobalt and copper nano oxides were studied in this research.
