Hollow structures are an extremely attractive and special feature of nanomaterials, and they have wide application prospects in several fields, such as photocatalysis, biomedicine, energy storage, and photoelectric conversion. The synthesis of hollow nanocrystals is mainly achieved via the fine control of material nucleation, particle growth, and surface connection. According to its growth mechanism, there are typically four strategies, namely, Kirkendall effect, Ostwald ripening, chemical erosion, and template-mediated synthesis. Hollow nanostructures based on iron oxides are environmentally friendly and have high specific capacity; they can address 96% of the volume change caused by the charge-discharge cycles in lithium-ion batteries (LIBs). Thus, they have attractive application prospects as anode materials for LIBs. In this review, advances in the synthesis of hollow nanostructures based on iron oxides are summarised, and their application prospects as anode materials for LIBs, based on the above four strategies, are discussed.
