چکیده مقاله :
In this work, synthesis of a new magnetic catalyst, Fe3O4@IL-APD-CoCu, and its application in the reduction of nitrophenol compounds, decolorization of dyes, and degradation of tetracycline is studied. The structure of the catalyst was identified and analyzed by various techniques such as TEM, XRD, XPS, FT-IR, and UV-vis. In the following, catalytic performance in the reduction of nitrophenol compounds including 4-nitrophenol (4-NP), 3-nitrophenol (3-NP), and 2-nitrophenol (2-NP), decolorization of organic dyes such as methyl orange (MO), methyl red (MR), and rhodamine B (Rh B) and degradation of tetracycline were investigated and the results showed that the mentioned compounds participated properly in the reduction reaction in the presence of the catalyst. The research results showed that bimetallic cobalt-copper catalyst has a much better performance than monometallic cobalt and copper catalysts. The recyclability of the desired catalyst was also investigated and showed 14 runs of recyclability without a significant reduction in catalytic activity.
