A highly ordered Ge-incorporated akaganeite with the atomic ratio of Ge/Fe = 0.14 and Cl/Fe = 0.11 was firstly synthesized through hydrolysis and acidification of a mixed solution of FeCl3·6H2O and TEOGe (Ge(OC2H5)4) under the α-Fe 2O3 synthesis conditions. The newly synthesized Ge-akaganeite shows a monodisperse nanorod with 15-17 nm in width and ∼200 nm in length, the distinctly enhanced structural ordering and stability, and substantial differences in crystallographic and magnetic features. Here we propose a hypothetical akaganeite model with Ge occupying the tunnel sites as Ge(OH)40 based on crystallographic and chemical analyses.
