A novel technique by the citrate pyrolysis for preparation of iron oxide nanoparticles

A novel technique by the citrate pyrolysis is developed to prepare metal oxide nanocrystals. In this paper details on synthesizing iron oxide nanoparticles through this method is described. The structure and morphology of nanoscale products have been characterized by powder X-ray diffraction (XRD) and scanning electron microscopy (SEM). The obtained iron oxide particles have two lattice types and a mean particle size distribution of 20 and 50 nm, respectively.
