Synthesis of magnetic iron oxide (Fe3−xO4) nanosheets using iron oleate complex via hydrothermal methods were investigated, and the obtained Fe3−xO4 nanosheets had 500 to 2000 nm in lateral size. Since the thickness of Fe3−xO4 nanosheets was 10 nm, the estimated aspect ratio was 50 to 200. On the other hands, Fe3−xO4 nanocubes are obtained only in solvothermal treatment. These results suggest that liquid-liquid interface between aqueous solution and non-polar organic solvent plays an important role to synthesize iron oxide nanosheets with large lateral dimensions.
