Abstract
In this work, the Fe3O4 magnetic nanoparticles with different shapes and average sizes of 15 to 180 nm were synthesized by an electrooxidation method, the size and shape of the particles were experimentally controlled by tuning the parameters of potential and electrolyte temperature, and its structure was conducted by XRD, forming the Fe3O4 phase. FT-IR confirmed that the stabilizer molecules can cover the particle surfaces. The resultant TEM and SEM showed that the particles have polycrystalline structure, and their size, shapes and surface morphology change dramatically under different potentials and temperatures. Also the particle size dependency was obtained by using UV-Vis spectroscopy, indicating that their maximum absorption wavelength and peak width decrease with increasing temperature and potential.
