Biosynthesis and characterization of Ag/MgO nanocomposite and its catalytic performance in the rapid treatment of environmental contaminants

摘要

In this work, the fabrication of Ag nanoparticles (NPs) decorated on MgO has been carried out. In this technique, Acalypha hispida extract has been employed as a renewable, mild reducing and stabilizer agent. The Ag/MgO nanocomposite formation was confirmed by different characterization methods. Afterwards, the catalytic activity of Ag/MgO nanocomposite was examined in NaBH4-assisted reduction of methylene blue (MB), 4-nitrophenol (4-NP), methyl orange (MO) and 2,4-dinitrophenylhydrazine (2,4-DNPH). The Ag/MgO system has advantages such as high catalytic performance, high stability and facile reusability.
