Preparation and characterization of PVC/NiFe2O4/Fe2O3 composite: Catalytic activity for synthesis of Arylidene Barbituric acid derivatives

Abstract

PVC/NiFe₂O₄/Fe₂O₃ compositewas successfully synthesized and characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray powder diffraction (XRD), and scanning electron microscopy (SEM). Also, the catalytic activity of PVC/NiFe₂O₄/Fe₂O₃ has been considered in the synthesis of two arylidene barbituric acid derivatives. The FT-IR and XRD results confirmed the synthesis of PVC/NiFe₂O₄/Fe₂O₃ composite. According to Scherre equation and the main peak at about 2θ = 41.72º, the average crystalline size of the nanoparticles determined at about 75 nm. Catalytic activity results show that the as-prepared composite is as an efficient catalyst. This study suggests that other PVC composites could be explored as a new catalyst for synthesis of other arylidene barbituric acids.
