Abstract This research unveils an innovative approach to green synthesis, detailed characterization, and multifunctional exploration of bio-functionalized zinc oxide nanoparticles (PN/ZnO NPs) adorned with phytochemicals from Piper nigrum (PN). Employing extensive suite spectroscopic techniques physicochemical methods, including UV–vis spectroscopy, field emission scanning electron microscope (FESEM), high-resolution transmission (HRTEM), energy dispersive x-ray (EDX) Fourier-transform infrared (FTIR), diffraction (XRD), Brunauer–Emmett–Teller (BET) analysis, the study delves into unique properties PN/ZnO NPs. XRD confirms development wurtzite phase a crystallite diameter 47.77 nm. FTIR reveals ZnO functionalization by PN’s phytochemicals, while FESEM HRTEM suggest diverse architectural features. Selected area patterns authenticate crystalline structure. BET analysis showcases large specific surface 80.72 m 2 g −1 mesoporous The absorption peak at 372 nm band gap ( E ) 3.44 eV validate NP formation. catalytic performance is demonstrated through degradation commercial reactive yellow-17 (RY-17) dye, (dosage 300 mg l achieving 94.72% removal dose 120 . Pseudo-first-order kinetics govern photodegradation process. PN-ZnO NPs showcase potent antimicrobial efficacy against both gram-negative gram-positive bacteria, varying clearance zones. stands as impactful exploration, integrating versatile functionalities
