| We were able to synthesize uniform iron oxide hydroxide (goethite) nanotubes having a parallelogram cross section from the reaction of hydrazine with Fe(III)-oleate complex immobilized in reverse micelles. The edge dimensions and lengths of the nanotubes were easily controlled by varying the reaction conditions, such as the kinds of Fe-carboxylate complex and carboxylic acid, and the aging time. The current synthetic procedure is very simple and highly reproducible and, consequently, readily applicable to large-scale synthesis. For example, when we conducted the synthesis using 5 times more reagents than the amounts indicated above, we were able to synthesize as much as 7.2 g of the goethite nanotubes with a uniform edge dimension of 7 nm |
