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.
