Shape-controlled Fe3O4 nanostructure has been successfully prepared using polyethylene glycol as template in a water system at room temperature Different morphologies of Fe3O4 nanostructures, including spherical, cubic, rod-like, and dendritic nanostructure, were obtained by carefully controlling the concentration of the Fe3+, Fe2+, and the molecular weight of the polyethylene glycol Transmission Electron Microscope images, X-ray powder diffraction patterns and magnetic properties were used to characterize the final product This easy procedure for Fe3O4 nanostructure fabrication offers the possibility of a generalized approach to the production of single and complex nanocrystalline oxide with tunable morphology.
