This work focuses on the green synthesis of zinc oxide nanoparticles (ZnO NPs) to be used as a photocatalyst, preparing blueberry (Vaccinium corymbosum) extract reducing agent, chloride precursor, and NaOH precipitating agent (1, 7 14 M). Characterization techniques included X-ray diffraction (XRD), transmission electron microscopy (TEM), ultraviolet-visible (UV-Vis), Fourier-transform infrared (FTIR), photoelectron (XPS), Raman spectroscopy. The XRD analysis confirmed hexagonal wurtzite crystalline structure ZnO NPs, while SEM TEM revealed flower-like morphology. Moreover, NPs exhibited band gap energy in range 3.17 3.27 eV, depending concentration NaOH. Regarding photocatalytic activity, synthesized showed efficiency greater than 90%, degrading malachite (MG) dye 60 min under sunlight. proposed mechanism includes reactive oxygen species (ROS) generation (hydroxyl radicals (OH•) superoxide (O2−)). also that maintained structural integrity after repeated cycles, emphasizing their stability suitability for practical applications.

Abstract Green synthesis of zinc oxide nanoparticles was carried out using Prosopis juliflora bark extract and Cordia dichotoma leaf with acetate precursor in the presence 2 M NaOH solution. The prepared were characterized by Powder X-ray diffraction (PXRD), UV-visible absorption spectroscopy, Fourier transform infrared spectroscopy (FTIR), Photoluminescence (PL) to study its structural optical properties. studies confirmed hexagonal wurtzite phase samples an average crystallite size calculated Scherrer equation 38.22 nm 29.95 for mediated (PJZ) (CDZ) NPs respectively. Williamson-Hall modified form uniform deformation model (UDM), stress (USDM) energy-density (UDEDM) determine micro-strain ZnO nanomaterials. Tauc’s plot method revealed energy gap value 2.86 eV PJZ sample 2.95 CDZ due quantum confinement effect. FTIR spectra recorded ascertain biomolecules involved green synthesis. PL showed a strong UV emission peak around 370 visible broad band at 554 which is singly ionized oxygen vacancies. An effective prepare nanomaterials efficient antioxidant potential reported this study. current has also demonstrated that small particle responsible significant antibacterial activity against both gram-positive gram-negative bacteria.
