Phase-pure α-Fe2O3 nanoarchitectures with both a mesoporous morphology and crystalline domain structure can be readily produced in the form of thin films through coassembly of hydrated ferric nitrate with a poly(ethylene-co-butylene)-block-poly(ethylene oxide) diblock copolymer. These novel materials exhibit enhanced lithium-ion storage capabilities and excellent cycling stabilities by suppressing the irreversible phase transformations that are observed in microcrystalline α-Fe2O3.
