Achieving the smallest crystallite/particle size of zinc oxide nanoparticles (ZnO NPs) reported to date, measuring 5.2/12.41 nm with Justicia adhatoda (J. adhatoda) leaf extract, this study introduces a facile green synthesis. Utilizing aqueous J. extract as both reducing and stabilizing agent, method leverages plant's rich phytochemical composition produce highly crystalline morphologically controlled ZnO NPs. This precise particle control highlights effectiveness synthesis process in morphological tuning. The synthesized NPs were thoroughly characterized using XRD, UV-vis spectroscopy, FTIR, FESEM, HRTEM, which collectively revealed superior crystallinity, morphology, unique surface properties conferred by bio-capping. photocatalytic performance these biogenic was evaluated for degradation two model pollutants: malachite (MG), synthetic dye, 4-nitrophenol (4-NP), toxic organic compound. exhibited exceptional efficiency, achieving 99.8% MG within 180 minutes demonstrating rapid reduction 4-NP 4-aminophenol reaction rate constant 0.245 min-1 under UV sunlight irradiation. Mechanistic studies attributed high reactive oxygen species (ROS) generation electron-hole pair interactions, supported improved charge separation area. work not only establishes potential adhatoda-mediated addressing persistent pollutants but also sets benchmark size-controlled By delivering scalable eco-friendly water remediation technologies, advances nanotechnology.

Abstract This study introduces an eco-friendly and simple approach for synthesizing zinc oxide (ZnO), copper (CuO), ZnO-CuO composite nanoparticles using orange peel extract, minimizing the use of harmful chemicals while enhancing their antibacterial photocatalytic properties. The were annealed at 400 °C 2 h in air. Characterization was conducted x-ray Diffraction (XRD), Dynamic Light Scattering, Fourier Transform Infrared Spectroscopy (FTIR), UV-visible Spectroscopy. XRD revealed that ZnO CuO crystallized hexagonal wurtzite monoclinic structures, respectively, with crystallite size lattice strain analyzed through Williamson–Hall, Size-Strain Plot, Halder-Wagner, Wagner-Aqua methods. FTIR spectra confirmed presence Zn-O bonds, verifying successful synthesis. optical bandgaps measured 3.07 eV ZnO, 2.702 CuO, 1.842 nanocomposite. Antimicrobial efficacy, assessed via disc diffusion method, showed exhibited enhanced activity against both gram-positive gram-negative strains compared to individual CuO. Photocatalytic experiments demonstrated under sunlight, nanocomposite achieved 78% degradation 10 ppm methylene blue within 90 min, outperforming (55%) (38%). These results highlight composite’s potential effective dye environmental remediation applications.
