Bicrystalline Hematite Nanowires

The Journal of Physical Chemistry B, 2005
Bicrystalline nanowires of hematite (alpha-Fe(2)O(3)) have been successfully synthesized by the oxidation of pure iron. The product was characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy (TEM), high-resolution TEM in combination with focal series reconstruction, energy-dispersive X-ray spectroscopy, and ...

Ultrathin Polycrystalline Hematite and Goethite−Hematite Core−Shell Nanorods

Langmuir, 2009
We have developed a facile synthesis route to 1D structures of ultrathin polycrystalline hematite and goethite-hematite core-shells. One-dimensional structures of pure hematite and the goethite-hematite core-shell with very small diameters were synthesized in aqueous solution at low temperature with a simple, rapid method based on the oxidation of ...
