Description
This study describes a green and sustainable method of producing copper oxide nanoparticles (CuO NPs) using Combretum indicum leaf extracts in aqueous and alcoholic solvents. The synthesis parametersextract concentration and pHwere optimized to achieve high yield (85%), small crystallite size (2035nm), and monodisperse particles. FTIR, PXRD, SEM, TEM, and UVvisible spectroscopy indicated the synthesis of monoclinic CuO NPs with mixed morphologies (spheres, rods, and plates), as well as phytochemical surface functionalization. The NPs exhibited multifunctional performance: alcoholic extract-derived CuO NPs showed exceptional dye adsorption (?95% removal of Methyl Orange in 180min), while aqueous extract-derived NPs demonstrated high oil adsorption (90%). Antimicrobial activity was strain specific, with significant efficacy against Streptococcus mutans (3.7mm zone of inhibition). The solvent-dependent surface chemistryhydrophilic for dye removal and hydrophobic for oil adsorptionhighlights the potential for tailored environmental remediation. This eco-friendly approach offers a promising route for synthesizing versatile CuO NPs with applications in wastewater treatment and antimicrobial strategies. 2025 Wiley-VCH GmbH.
