|Abstract:||Hollow iron oxide tetrapods are synthesized by exposing iron precursors to hollow ultrathin PtS tetrapods. Surprisingly, the heterogeneous nucleation and growth of iron takes place exclusively within the PtS interior. Oxidation of the resulting iron tetrapod produces a hollow iron oxide shell via a shape-preserving Kirkendall effect which preserves the morphology of the original tetrapod with remarkably high precision, offering a robust synthetic route to hollow iron oxide nanostructures of unprecedented geometry. © 2013 WILEY-VCH Verlag GmbH & Co.
