Abstract

Moringa oleifera leaves extract Yemeni was used for green synthesis of copper oxide nanoparticles (CuO). The obtained copper oxide nanoparticles were characterized using ultraviolet–visible spectroscopy (UV–VIS), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDX), and X-ray diffraction (XRD). The aqueous suspension of (CuO NPs) showed a UV-Vis. absorption maxima peaks at 236 and 240 nanometers respectivel primarily in  its formation. The FTIR analysis to be confirmed functional groups of biosynthesized CuO NPs the absorption band at 608cm^-1. The XRD analysis revealed that the biosynthesized NPs appear to be more than crystalline of the copper oxide nanoparticles. The characteristic peaks obtained by EDX analysis icon firmed the presence of the element copper (89.8), and the element oxygen (10.2). SEM images show that the particles are round, granular, and nanosized and the nanoparticle has more aggregation ,and conglomeration. Extraction of moringa leaves serves as a promising agent for the balance of particle size. The result of medical value shows significant antibacterial activity.
