Abstract

In the realm of nanotechnology, it is crucial to establish procedures for the accurate manufacture of metallic nanoparticles with specific sizes, shapes, and contents. Metallic nanoparticles possess unique optical, electrical, and magnetic properties that set them apart from bulk metals. One required method and modern technology for synthesizing copper oxide nanoparticles is green synthesis, which involves using lemon leaves, one of the most important medicinal plants. The study aims to manufacture copper oxide nanoparticles using lemon leaf as a medicinal plant and improve a study to characterize the nanoparticles. In our work, copper oxide nanoparticles are synthesised, optimised, and then characterised using UV spectroscopy, SEM, and XRD. The results showed that its peak wavelength is 272nm, the optimisation for PH 8 is 90 °C, the time is 15 min, and the concentration ratio of a metal ion is 5 ml. Characterization SEM is (69–77), and XRD analyses have 2 values of 28nm.
