Abstract
The increasing environmental issues and anticipated energy crisis highlight the urgent need for a cost-effective and efficient photocatalyst that responds to UV light for contaminant degradation. This work presents a novel approach to synthesizing Zea mays L.-loaded silver oxide nanoparticles (Ag2O) by chemically depositing a thin coating of Ag2O NPs onto the surface of Zea mays L. with two ratios (e.g., 5 & 10%) to form novel cost-effective core-shell Ag₂O/Z nanostructures. To assess morphology, and elemental composition, the synthesized composite was examined using high-resolution transmission electron microscopy (HR-TEM) and scanning electron microscopy (SEM) together with energy dispersive X-ray (EDX) spectroscopy. The effectiveness of 10% Ag2O/Z as a catalyst and adsorbent was evaluated based on several criteria, including pH, beginning concentration of the target dye, and the…
