Uniform iron oxide hydroxide (goethite) nanotubes having a parallelogram cross section were prepared by the reaction of hydrazine with Fe(III)-oleate complex immobilized in reverse micelles. The current synthetic procedure is very simple and highly reproducible and, consequently, readily applicable to large-scale synthesis. Using the reverse micelle method, iron oxide nanocrystals having various crystal structures such as magnetite and hematite were able to be obtained by varying the reaction conditions. |
