Rod-shaped magnetite nano/microparticles synthesis at ambient temperature

Abstract

Here, we reported room temperature synthesis of Fe 3O 4 rod-shaped nano/microparticles by chemical reduction method from FeCl 3 precursor and NaBH 4 as the reducing agent in the presence of the pyrrole as a capping agent. The magnetic Fe 3O 4 particles were characterized by several methods, such as SEM, XRD, FTIR, and TGA. The average aspect ratio of Fe 3O 4 rod-shaped particles was 2.8. These particles were redispersed in deionised water to form a colloidal solution and showed magnetic properties. This economical synthesis route is scalable, and Fe 3O 4 particles can be exploited for various applications such as MRI contrast enhancement, biodiseperations, Ni-Fe batteries, and as a catalyst. © 2013 Balaprasad Ankamwar and Ashwini Thorat.
