[Display omitted] •Green synthesis of Ag NPs/seashell by extract of seeds of B. persicum.•Ag NPs/seashell was characterized by FT-IR, FE-SEM, EDS, TEM, TG-DTA, XRD and UV–Vis.•Catalytic reduction of 4-nitrophenol, Methyl Orange, Congo Red and Methylene Blue.•The catalyst could be easily recovered and reused several times. In the present work, silver nanoparticles were immobilized on the surface of seashell using Bunium persicum seeds extract as a reducing and stabilizing agent. The seashell supported silver nanoparticles was characterized by FT-IR spectroscopy, X-ray diffraction (XRD) pattern, field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDS), transmission electron microscopy (TEM) and Thermogravimetric-differential thermal analysis (TG-DTA). The diameter of Ag NPs on the seashell was predominantly found within the range 20–50nm. The catalytic performance of the prepared catalyst was investigated for reduction of 4-Nitrophenol (4-NP), Methyl Orange (MO), Congo Red (CR) and Methylene Blue (MB) at room temperature. It was found that the Ag NPs/seashell is a highly active and recyclable catalyst for related reactions and can be recovered and reused several times without significant loss of its catalytic activity.
