Most of the dyes are toxic to aquatic organisms. Thus, there is a drastic need to develop ecofriendly treatment methods for the elimination of these pollutants from the environment, because of their toxicity and carcinogenic properties. Thus, the need for ‘greener’ methods or chemical products that reduce or eliminate the use and generation of hazardous compounds is essential. Graphene Oxide has been a lot of attention because of its unexampled properties, such as large surface area and high conductive and electromagnetic parameters and so on. Fe3O4 nanoparticles are superparamagnetic and have been studied in many aspects such as structural, morphological, optical, magnetic and catalytic properties and superconductivity. GO/Fe3O4 nanocomposites were synthesized to incorporate the properties of both Fe3O4 and graphene. In this work, a Cu(Ⅱ) Schiff base complex supported on magnetic GO and used as efficient nanocatalyst for reduction reaction. Also, the synthesized nanocatalyst could be separated easily from the reaction mixture using an external magnet and reused for several consecutive times for dye reduction.
