The current investigation documented the construction of eco-friendly zinc oxide nanoparticles (ZnO NPs) using Araucaria heterophylla leaf extract. synthesized material is characterized through various techniques. x-ray diffraction (XRD) spectrum depicted prominent peaks. 31.9 nm was determined to be average particle size. spherical and aggregated ZnO NPs were visible in scanning electron microscope (SEM) results. Energy dispersive (EDX) spectra results confirmed existence Zinc oxygen elemental FTIR extract elaborated on participation phytochemical constituents. Catalytic activity investigated for Methylene blue (MB) Congo red dye (CR). For both dyes, best outcomes are achieved when concentration 5 mg/L adsorbent dose 10 mg, with a contact duration 20 min. Adsorption isotherms (Langmuir Freundlich) kinetic models including pseudo first order, Elovich, intraparticle diffusion, Boyd also applied degradation studies. Antioxidant potential assessed three different approaches: total antioxidant, 2,2-diphenyl-1-picrylhydrazyl (DPPH) activity, phenolic contents. scavenging free radical percentage calculated 82 ± 0.07 1500 μg/mL concentration. In comparison standard, antioxidant 0.569 (% w/w). While contents 244 1.4 mg GAE/g. Hence, this study demonstrated that biosynthesized exhibit adequate environmental remediation
