Nanoparticles possess unique optical, mechanical, magnetic, electronic, and chemical properties, enabling their use in various fields. Green synthesis, leveraging plant extracts, offers an eco-friendly and cost-effective alternative. This study synthesized cobalt oxide nanoparticles (Co3O4 NPs) using jujube leaf extract and characterized them using UV-Vis, FT-IR, XRD, and SEM. UV-Vis analysis revealed absorption peaks at 212 nm and 196 nm, corresponding to particle sizes of 40-79 nm. FT-IR identified functional groups in the extract, while XRD confirmed the crystal structure and estimated crystallite sizes using the Debye-Scherrer equation. The Co3O4 NPs exhibited strong photocatalytic activity and significant visible light absorption, supported by electronic band structure analysis confirming their half-metallic nature. These findings underscore the material's environmentally friendly synthesis and potential for advanced photocatalytic applications
