Synthesis of Cobalt Ferrite Nanowires Using FeOOH as a Template
In this work, cobalt ferrite nanowires were chemically synthesized using FeOOH array a template. The FeOOH nanoarray was obtained by the hydrolysis and precipitation of Fe+3, from FeCl3.4 H2O. The cobalt ion (Co+2) was added in order to make it interact with FeOOH nanorods of 20 nm of diameter and 150 nm of length. These nanorods are grouped into packages having different orientations due to the interaction with the cobalt ions. The arrays were calcinated at 700 and 800 °C to obtain cobalt ferrite nanowires with 70 nm of diameter and some micrometers of length. The morphology and the average size of the nanorods and nanowires were determined using Field Emission Scanning Electron Microscopy (FESEM). The Fourier Transform Infrared Spectroscopy (FTIR) was used to study the interaction between the nanorods and the cobalt ions. The phases of the material were identified using X-ray Diffraction.
