Nowadays, the industrial wastewater pollutants including toxic dyes and pathogenic microbes have caused serious environmental contaminations human health problems. In present study, eco-friendly facile green synthesis of Ag modified ZnO nanoparticles (ZnO-Ag NPs) using Crataegus monogyna (C. monogyna) extract ([email protected] is reported. The morphology structure as-biosynthesized product were characterized by field emission scanning electron microscopy (FESEM), X-Ray diffraction (XRD), differential reflectance spectroscopy (DRS), dynamic light scattering (DLS), transmission (TEM), Fourier-transform infrared (FT-IR), energy-dispersive X-ray (EDS) techniques. TEM FESEM images confirmed oval spherical-like products with a size 55–70 nm. EDS analysis presence Zn, Ag, O elements in biosynthesized product. photocatalytic results showed [email NPs degraded (89.8% 75.3%) (94.2% 84.7%) methyl orange (MO) basic violet 10 (BV10), under UV sunlight irradiations, respectively. exhibited enhanced catalytic activity towards organic pollutants, better performance than pure irradiations. This was probably due to silver as plasmonic material. Antibacterial performed against different bacteria. high antibacterial K. pneumoniae, S. typhimurium, P. vulgaris, mitis, faecalis MIC values 50, 12.5, 12.45 µg/mL, All all, investigation suggests promising method achieve high-efficiency performance.
