In our present work, for the first time we reported an easy, inexpensive and eco-friendly method for the preparation of silver nanoparticles (Ag NPs) supported on nano aluminum oxide (Al2O3) using Bryonia alba leaf extract. The plant extract as a mild, renewable, non-toxic reducing and stabilizing agent has an important role in anchoring of Ag NPs on the nano Al2O3. The formation of Ag/Al2O3 NPs were proved through FT-IR, XRD, TEM, EDS and FE-SEM. The catalytic activity of the Ag/Al2O3 NPs has been tested as an affective and heterogeneous catalyst for the reduction of 4-nitrophenol (4-NP), 2,4-dinitrophenylhydrazine(2,4-DNPH) and degradation of the congo red (CR), methyl orange (MO), methylene blue (MB) and Rhodamine B (RhB) in the presence of sodium borohydride (NaBH4) at room temperature. The catalyst can be recovered and recycled multiple times without losing of activity.
