A Review on Iron Oxide-Based Nanoarchitectures for Biomedical, Energy Storage, and Environmental Applications

Iron oxide nanoarchitectures with distinct morphologies from 1D to 3D

have been developed using various wet chemical methods. They have

been employed for a wide range of applications, including energy storage,

biomedical, and environmental applications. The functional properties

of iron oxide nanoarchitectures depend on the size, shape, composition,

magnetic properties, and surface modification. To overcome the limitations

of pure iron oxide nanostructures, hybridizations with various inorganic

materials (e.g., silica, metals, metal oxides) and carbon-based materials

have been proposed. Herein, the recent advances in the preparation of

various iron oxide nanoarchitectures are reviewed along with their functional

applications in energy storage, biomedical, and environmental fields. Finally,

the effects of various parameters on the functional performance of iron oxide

nanostructures for these applications are summarized and the trends and

future outlook on the development of iron oxide nanoarchitectures for these

applications are also given.
