Abstract

This study involved the green synthesis of copper oxide and iron oxide nanoparticles three times using peel extracts from orange, cherry, and sidr. It also included creating a nanocomposite of these oxides from cherry and sidr peels. The nanoparticles' structural, biological, physical, and toxicity properties were analyzed. The impact of adding these oxides on concrete’s mechanical and physical properties was examined. Electrochemical tests showed that copper-iron oxide nanoparticles significantly improved the corrosion resistance of reinforcing steel, with a corrosion efficiency of 86.8% and a 57% improvement in concrete containing this oxide.
