Synthesis of Bio Nanocatalyst of ZnO Nanoparticles using Ocimum Basilicum Leaves

The aqueous extract of Ocimum basilicum leaves and zinc salts (zinc sulphate) was used as precursors in this investigation to create oxide nanoparticles. ultraviolet-visible spectroscopy, scanning electron microscopy, Dynamic light scattering (DLS) were characterize the produced (SEM), Energy-dispersive X-ray analysis (EDX), Because UV-Vis spectra exhibit absorption peaks 350 nm range. DLS prove nano size for prepared colloidal SEM investigations showed a spherical shape with an average (30-80) nm. Analysis (EDX) that elementary which are 31.8% oxygen is 21.3%.
