Abstract:
In recent years, there has been increasing emphasis on the design and application of graphene catalysts to reduce the quantity of toxic wastes. Among them, graphene-based polyaniline (PANI) nanocomposites have attracted a great deal of interest due to their new properties or enhancedperformance during the past few years. This is because PANI is a useful conducting polymer that hasbeen widely used for electronic, optical and electrochemical applications owing to its low cost. The structure of GO-PANI nanocomposite were completely characterized by Fourier Transforms Infrared Spectroscopy (FTIR), Field Emission Scanning Electron microscopy (FE-SEM), X-ray Diffraction (XRD), Thermal gravimetric analysis (TGA) and Energy Dispersive X-ray Spectroscopy (EDX). In this research, the synthesis of 1,4- dihydropyridine and hydroquinoline with nanocomposite polyaniline/graphene oxide is investigated through four component reactions between aldehydes, malononitrile/ethylcyanoacetate, anilines, dimethyacetylenedicarboxylate/ dimedone. Using heterogeneous catalyst in these reactions results higher activity, easy wourk up, high product yields and short reaction times.
