a new precursor for preparation of magnetite (fe3o4) nanoparticles
نویسندگان
چکیده
an anionic fe(ii) complex, (bmim)4[fe(cn)6] (where bmim is 1-butyl-3-methylimidazolium), was synthesized in ionic liquid [bmim][pf6] under reflux condition. the complex was characterized by elemental analysis and spectroscopic methods. the magnetite (fe3o4) nanoparticles were prepared by the hydrothermal and solvothermal (in ionic liquid [bmim][pf6]) methods from (bmim)4[fe(cn)6] as a precursor. the nanoparticles were characterized by x-ray diffraction (xrd), ft-ir, and scanning electron microscopy (sem). the results show that the preparation of magnetite using the solvothermal method in [bmim][pf6] has more advantages such as smaller size and high purity.
