摘要
This study reports the successful green synthesis of ZnO nanoparticles (NPs) utilizing an aqueous leaf extract of Olea europea L. The biogenic ZnO NPs were dreied at 100 °C and calcined at 450 °C. Their nanoscale dimensions were confirmed by UV-visible spectroscopy, scanning electron microscopy (SEM) revealing a size range of 40–60 nm, and X-ray diffraction (XRD) analysis confirming a hexagonal structure for both calcination processes. The ZnO particle size increased from 18.79 nm at 100 °C to 25.04 nm at 450 °C. The successful eco-friendly synthesis of ZnO NPs was further validated by FT-IR spectroscopy, which identified functional groups on the particle surface. Importantly, the ZnO NPs demonstrated remarkable efficiency in degrading Cephalexin, achieving a degradation rate of 95
