We report for the first time a novel precursor-templated conversion method for the controlled synthesis of hierarchically nanostructured magnetic hollow spheres assembled by Fe3O4 or γ-Fe2O3 nanosheets with a relatively high saturation magnetization. We synthesized hierarchically nanostructured hollow spheres organized by nanosheets of a layer-structured ferrous precursor by a microwave-assisted hydrothermal method in ethylene glycol (EG). Ferric chloride (FeCl3•6H2O) was used as the iron source, and EG acted as both a solvent and a reductant to reduce ferric salt to ferrous precursor in the presence of sodium hydroxide (NaOH) and sodium dodecyl benzene sulfonate (SDBS).
