title: Fabrication of hierarchical porous iron oxide films utilizing the Kirkendall effect.
abstract: Hierarchical porous iron oxide films with different morphologies have for the first time been fabricated through hydrothermal reactions between an iron substrate and iodine powder in water or ethanol, which can be explained by a mechanism analogous to the Kirkendall effect.
