Abstract
|
In our present work magnetic nanoparticles of cobalt ferrite have been synthesized by the immobilization of folic acid (FA) coated Co. The nano CoFe2O4@FA-Co catalyst was characterized by FT-IR, SEM, XRD, VSM, TGA, EDX, and ICP-OES. The obtained magnetic nano-catalyst complex as efficient and green heterogeneous system have been successfully applied for producing amines from nitro derivatives in green condition. These organometallic catalysts have high surface area and small size as a result show many benefits such as short reaction time, high yield, excellent purity, eco-friendly catalyst, easy workup procedure and recovery from the reaction mixture by external magnet and reusability for five continuous cycles without noticeable change in its catalytic activity.
