摘要：

A facile, anion-induced, one-pot solvothermal method was successfully developed to prepare two kinds of highly dispersed magnetic Fe3O4 submicrometer spheres at 200 degrees C in 12h. The diameters of the as-prepared Fe3O4 submicrometer spheres are similar to 500 and similar to 200nm, 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 74emu/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.
