Optimization Properties and Characterization of Green Synthesis of Copper Oxide Nanoparticles Using Aqueous Extract of Cordia myxa L. Leaves

摘要

Copper oxide nanoparticles (CuONPs) were green synthesized using aqueous extract of Cordia myxa L. leaves as reducing and capping agent. The synthesized nanoparticles were characterized by UV-visible spectrophotometer, FTIR, X-ray diffraction, scanning electron microscope and atomic force microscope. The prepared copper oxide nanoparticles showed surface plasmon resonance centered at 400 nm. The optimized condition for the synthesis of copper nanoparticles revealed that the aqueous extract of Cordia myxa L. leavesxopper sulfate ratio was 1:3, pH was 9 and copper sulfate concentration was 40 inM. FTIR results showed that stabilization and formation of CuONPs were due to phenolic groups and amines in plant extract. The XRD pattern showed that the particles are monoclinic in nature. The crystalline morphology and size of the nanoparticles were determined by scanning electron microscope. Presence of elemental copper was revealed by EDX analysis. Size range was from 20 to 106.81 nm was determined by atomic force microscope.
