Abstract Sepiolite possesses huge specific surface area, high porosity and a certain number of silicon hydroxyl groups on its surface. These groups provide more active sites for the combination of sepiolite with metal-oxides such as TiO₂, ZnO, Fe₂O₃ and so on. Therefore, silicate can be used as an attractive carrier for the composites with favorable adsorbability and catalysis. This paper mainly introduces different preparation methods of sepiolite-based metal oxide compounds such as sol-gel, precipitation, impregnation methods. The unique advantages such as improvement of specific surface area, pore volume and adsorptive capability are discussed. Furthermore, the application of sepiolite-based metal oxide compounds in liquid-phase and gas-phase photocatalysis area are reviewed, and the best degradation effect of these materials and some factors affecting the photocatalytic performance are introduced. Finally, a future development prospect for sepiolite-based metal oxide compounds as an ecological environment material is proposed.

Key words： sepiolite sepiolite-based metal oxide sepiolite/TiO₂ nanocomposites photocatalysis
