Abstract: Manganese oxide octahedral molecular sieves (OMS) has been widely used in heterogeneous catalysis, electrochemical and adsorption materials for its porous structure, mild surface acidity and basicity, mixed valence of Mn and excellent ion-exchange properties. In the paper, the chemical composition, pore structure, redox properties and acid-base properties were summarized, and the preparation methods such as hydrothermal, reflux, microwave, sol-gel and solid phase method were introduced. Manganese oxide octahedral molecular sieves can be applied in catalytic reactions such as CO catalytic oxidation, organic catalytic oxidation, activation and utilization of CO₂ and Fischer-Tropsch synthesis, and the activities would be higher for oxidation of CO and VOCs. It also has important application prospects in battery materials and adsorption materials. Finally, the existing problems in the study of manganese oxide octahedral molecular sieves are figured out. The future study should focus on exploring more efficient preparation methods, in-depth understanding of the catalytic mechanism of OMS, and further broadening the application.
