Abstract Water pollution, arising from the presence of toxic dyes and chemicals, is a global challenge, urging need for eco-friendly solutions in water decontamination. This study focused on synthesis copper oxide nanoparticles (CuO NPs), zinc (ZnO bimetallic CuO-ZnO nanocomposite (CZ NC) through an environmentally friendly method employing Tragia involucrata L. leaf extract. Comprehensive analysis structural optical properties involved using various analytical techniques such as XRD, FT-IR, XPS, UV-DRS, PL, FE-SEM, EDAX, TEM, SAED, zeta potential, TGA, BET. In comparison to pristine CuO ZnO NPs, CZ-NC demonstrated notably enhanced photocatalytic activity degradation Rhodamine B dye (RhB). The optimum conditions RhB were found be pH 9 catalyst dosage 1 mg/mL concentration 10 ppm. Under these conditions, high efficiencies 78%, 83%, 96.1% respectively over 105 min. Through LC-HRMS, identification products offered valuable insights into pathway degradation. Furthermore, toxicity intermediates, conducted ECOSAR software, indicated formation non-toxic by-products (ChV/LC 50 /EC > 100) after completion reaction. recycled catalysts exhibited sustained stability up 4 cycles, with only minor decrease 6.8%. confirms their catalytic efficacy purifying polluted water. research significantly contributes progress nanocomposites, enhancing realm environmental remediation.

The study explores the green synthesis and characterization of silver nanoparticles using Syzygium malaccense (L.) Merr. & L. M. Perry leaf extract (SM-AgNPs). UV-Visible spectroscopy confirmed reduction ions, showing an absorption peak at 406 nm. X-ray Diffraction (XRD) analysis revealed a face centered cubic structure with average particle size 23.55 Dynamic Light Scattering (DLS) zeta potential analyses indicated mean 40.1 nm surface charge −40.1 mV. FTIR identified functional groups involved in nanoparticle stabilization, while Energy Dispersive (EDX) content. Transmission Electron Microscopy (TEM) Atomic Force (AFM) provided detailed insights into morphology. Anticancer assays showed dose-dependent cytotoxicity against A549 cancer cells (LC50: 7.62 μg mL−1) minimal effects on L-132 normal 73.55 mL−1), highlighting selectivity. Additionally, SM-AgNPs increased Caenorhabditis elegans survival reduced paralysis under pathogenic bacterial exposure.
