Caffeine loaded magnetic nanoparticle was successfully synthesized and were characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDX), thermo gravimetric analysis (TGA), differential thermal analysis (DTA) and vibrating sample magnetometry (VSM). The resulting nanocomposite is shown to be an efficient catalyst in Knoevenagel condensations of various aldehydes under ultrasound irradiation.Caffeine loaded magnetic nanoparticle was successfully synthesized and were characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDX), thermo gravimetric analysis (TGA), differential thermal analysis (DTA) and vibrating sample magnetometry (VSM).
