Abstract:

Porous titania(TiO₂) materials have important values and potentials in the fields of catalysis, energy, sensing, etc., due to their outstanding physical and chemical properties. In some applications associated with heterogeneous reactions, porous structures of TiO₂ are advantageous because they have rich channels for mass transfer and surface active sites with tunable pore sizes. Nowadays, porous TiO₂ materials are constantly developed and optimized in order to promote their industry applications. This review focuses on the research progress of porous TiO₂ and their applications in photocatalysis, photogenerated electron storage, and gas sensing, in which the performance regulated through the design of structures and defects are introduced and discussed. Our research work about a series of porous TiO₂ functional materials based on photochemical synthesis is specially introduced. Finally, the key issues and development prospects of porous TiO₂ and their performances are also discussed.

Key words: porous titania, photocatalysis, photogenerated electron storage, gas sensing, performances
