A Green Approach to Synthesis of Co۳O۴ Nanoparticles from Jujube Leaf Extract: Comprehensive Characterization, Computational Insights and Photocatalytic Performance

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 (Co۳O۴ NPs) using jujube leaf extract and characterized them using UV-Vis, FT-IR, XRD, and SEM. UV-Vis analysis revealed absorption peaks at ۲۱۲ nm and ۱۹۶ nm, corresponding to particle sizes of ۴۰-۷۹ 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 Co۳O۴ 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
