Complexing-reagent assisted synthesis of α-Fe and γ-Fe2O3 nanowires under mild conditions

Abstract
α-Fe and γ-Fe2O3 nanowires were successfully synthesized from FeCl2 solution with 1,10-phenanthroline as complexing reagent via a simple, mild reduction or reduction–oxidization process. It was found that there existed some folded ribbon-like nanostructures as well as nanowires in the obtained α-Fe and γ-Fe2O3 products. Magnetic behavior of as-prepared α-Fe and γ-Fe2O3 nanowires was investigated by the temperature dependence of magnetization. The formation mechanism of α-Fe and γ-Fe2O3 nanowires was also proposed.
