One-step Electrochemical Preparation of Oleic Acid Capped Superparamagnetic Iron Oxide Nanoparticles in Ethanol Medium and its Characterization

In this paper, oleic acid capped iron oxide nanoparticles (oa-ionps) is prepared through a simple and efficient electrochemical synthetic route. oa-ionps were synthesized from the fe(iii) nitrate (0.005 m) and 10 cc oleic acid dissolved in ethanol (96%) solution with applying 5 ma cm^–2. the prepared ionps were characterized by different techniques of xrd, fe-sem, tem, ft-ir, tga, dls and vsm. the oa layer on the surfaces of ionps was confirmed by ft-ir, dls and dsc-tga analyses. the magnetic analysis by vsm revealed that the prepared oa-ionps exhibit negligible mr and ce values at the condition of h→0, implicating their superparamagnetic nature.
