Abstract

A facile, anion-induced, one-pot solvothermal method was successfully developed to prepare two kinds of highly dispersed magnetic Fe₃O₄ submicrometer spheres at 200°C in 12 h. The diameters of the as-prepared Fe₃O₄ submicrometer spheres are ~500 and ~200 nm, respectively. With the guidance of OAc ⁻ ions, the size and morphology of the Fe₃O₄ spheres could be well controlled. The saturation magnetization of the Fe₃O₄ spheres was measured to be 84 and 74 emu/g, respectively. The assembly of tiny precursor nuclei into the Fe₃O₄ spheres relies on Ostwald ripening. The synthesized Fe₃O₄ submicrometer spheres show good magnetic response, good water solubility, and uniform size.
