Iron-base inorganic mesoporous materials have attracted a lot of attentions recently due to their environmental-benignancy, cost-efficiency, and unique properties of magnetism and chemical activity, which allow them to find potential applications in different areas. In this paper, the recent progress in synthesis of iron-based inorganic mesoporous materials as well as their applications has been reviewed, with an emphasis on the synthetic routes and structural properties of various iron-based inorganic mesoporous materials (i.e., mesoporous iron oxyhydroxides, mesoporous iron oxides, mesoporous ferrosilicates, mesoporous iron phosphates, iron-based mesocrystals, mesoporous Fe/Si (C, Al, Ti) composites, etc.). In addition, their applications in catalysis, adsorption, gas-sensing, lithium-ion batteries, pharmacies, host-guest synthesis and other fields have been summarized and discussed. The current research problems of iron-based inorganic mesoporous materials and several future research directions have also been addressed.
