Abstract: Nanoparticles are nanostructures with at least one dimensionbeing less than 100 nm.In this research, nano magnetic Fe3O4@collagen was prepared and characterized by Fourier transforms infrared spectroscopy (FT-IR) spectra, Scanning electron microscopy (SEM) images, energy dispersive X-ray spectroscopy (EDX) spectra, X-ray diffraction (XRD) measurements.Fe3O4@collagen is a new and greennano catalysis and using in synthesis of benzimidazoles and benzithiazoles.This method offers several advantages including high yields, short reaction times, easy work up procedure, reusability of catalyst and environmentally benign reaction conditions.
