This work concentrated on the decoration of AgNPs to yellow phosphorus slag (YPS) using both chemical (NaBH ) and biological ( nut and leaf extracts) reducing agents, as well as its use as antibacterial and enhancement additives for organic coatings based on acrylic emulsion resin. It is the first study about the decoration of AgNPs on the surface of YPS using bio-reduction agents ( nut and leaf extracts). The characteristics of YPS decorated by AgNPs (YPS@AgNPs) were determined using attenuated total reflectance infrared spectroscopy, scanning electron microscopy, X-ray diffraction, ultraviolet-visible spectroscopy and dynamic light scattering methods. To quantify the amount of AgNPs in YPS@AgNPs, atomic absorption spectroscopy was used. The results of YPS@AgNPs fabrication confirmed that the above green reduction agents had a higher efficiency and were more suitable than the chemical reduction agent (NaBH ). Moreover, the ability to inhibit the growth of bacteria strains of YPS@AgNPs using the leaf extract as a reducing agent gave the best result among the three agents. In particular, the bactericidal activity of YPS@AgNPs against the new marine bacterium, , was evaluated, and it was found that YPS@AgNPs can inhibit the growth of an antibiotic-resistant bacterium, . They enhance not only the mechanical properties but also the bactericidal ability of the water-borne acrylic resin coating.
