摘要

Copper oxide nanoparticles (CuO NPs) are emerging as promising multifunctional agents for agriculture and environmental remediation. Here, we report the laboratory-scale synthesis of sodium dodecyl sulfate (SDS)-stabilized CuO NPs via a co-precipitation method, optimising NaOH concentrations to adjust particle characteristics. X-ray diffraction (XRD) confirmed a crystalline monoclinic structure, while scanning electron microscopy (SEM) revealed well-dispersed, spherical nanoparticles ranging from ~ 27 to 95 ± 5 nm. SDS stabilization effectively prevented agglomeration and enhanced nanoparticle dispersibility. UV–Vis spectroscopy revealed optical band gaps ranging from 4.16 to 4.52 eV, values higher than typical bulk CuO likely due to nanoscale effects and SDS interactions. The nanoparticles demonstrated approximately 62.2% and 66.4% mycelial growth inhibition against Pythium myriotylum and Phytophthora capsici, respectively, under in vitro conditions. Additionally, the SDS-CuO NPs achieved up to 94% degradation of methylene blue under UV light after 90 min, indicating effective photocatalytic activity in model dye systems. These findings suggest the potential of SDS-CuO NPs for dual applications, though further work is needed to evaluate reusability, environmental impact, and field-level performance.
