Özet

In this research, graphene oxide -polyaniline -lignosulfonate (GO-PANI-LS) nanocomposite was synthesized successfully and it was used as an effective recyclable catalyst for the synthesis of polysubstituted pyridines. Characterization of the prepared nanocomposite was carried out by Fourier transform infrared radiation (FT-IR), X-ray diffraction patterns (XRD), Energy-dispersive x-ray spectroscopy (EDX), Field-emission scanning electron microscopy (FE-SEM) and Thermogravimetric analysis (TGA). The first report of using this nanocomposite as a heterogeneous catalyst in synthesis of polysubstituted pyridines, Eco-friendly, high catalytic activity of catalyst, simplicity of procedure, mild reaction conditions, easy recovery and considerable reusability without significant loss of performance are advantages of this method.
