Green Synthesis of CuO nanoparticles with walnut leaf extract

Nanoparticles have attracted the curiosity of both scientific and industrial interests, Due to various their unique features and numerous possibilities. CuO nanoparticles have piqued scientists' interest due to their diverse features, including optical and electrical capabilities, as well as a wide range of applications, including photocatalysis, antimicrobial, gas sensors, and solar cells. Therefore, CuO nanoparticles were synthesized using a green technique, which is both environmentally friendly and cost-effective, using walnut leaf extract, which has excellent antioxidant effects as well as reducing and stabilizing capabilities. The findings revealed that using a green process provides a number of advantages, including high-purity nanoparticle creation and structure control. Scanning electron microscopy (SEM) was used to study the nanoparticles' structure, and the synthesis of CuO nanoparticles with x crystal size and y shape was confirmed
