چکیده مقاله:

Recently, graphene oxide (GO) has been extensively investigated as a new class of promisingsupport or catalysts due to their high stability and high specific surface area [1]. Despite thehigh catalytic activities of GO or (RGO), their separation techniques are consuming a veryenergy and a long time. Fortunately, this technical limitation can be overcome by introducingFe3O4 magnetic nanoparticles onto the surface of the GO [2,3]. This kind of supporting allowscatalyst to be easily separated from the reaction mixture by an extra magnet and reused severaltimes. There is a drastic need to develop a newer eco-friendly method for the synthesis ofmetal/GO nanocomposites under a mild condition. In this article, GO and SOCl2 were addedto generate GO-Cl and then melamine was added to GO-Cl under nitrogen atmosphere for 8 hat 60°С.The obtained product was treated with methyl methacrylate and ethylenediamine.Then AgNO3 was added into the catalyst and nanocatalyst was prepared by plant extract(Fig.1). At the end, magnetic nanocomposite was fabricated by Fe3O4 nanoparticles. The resultsshow that the nanocomposite can be employed as a magnetically recycled catalyst for thereduction of organic dyes such as methylene blue, methyl orange, rhodamine 6G and 4-nitrophenol in water at room temperature.
