Abstract This study addresses the pressing issue of environmental pollution caused by antibiotics and synthetic dyes in aquatic ecosystems, presenting a novel approach for their efficient photocatalytic degradation. Zinc oxide (ZnO)-based nanoscale photocatalysts, including ZnO nanoparticles (NPs) ZnO/Ag nanocomposite heterostructure (NCH), were synthesized through an innovative eco-friendly method utilizing extract derived from discarded lemon peels as biogenic reducing agent. The materials extensively characterized UV spectrophotometry, X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR). results confirmed different morphologies NPs NCH, with average sizes 20 nm 42 nm, respectively. Notably, NCH exhibited optical bandgap energies 3.2 eV 2.85 eV, respectively, signifying potential photocatalysts. Under natural sunlight irradiation, these demonstrated exceptional activity, achieving remarkable 98.8 % degradation rate metronidazole 90 ciprofloxacin just 12 min. Furthermore, effectively removed 84 Toluidine Blue 77 Congo red after 120 min, while enhanced rates to approximately 90.5 86 Red. research highlights significant physicochemical properties synthesis methods employed, positioning sustainable nanomaterials promising solutions mitigating effectively.
