In addition to focus on the improvement of visible light absorp-tion, more and more researchers paid attention to the modificationof microstructure of TiO2, such as the TiO2with mesoporous struc-ture. Both high specific surface area and porous frameworks areimportant characteristics of mesoporous TiO2, which may exhibitlarge pore volume or large pore diameter [10] and are beneficialto such applications as photocatalytic activity or electrochemicalactivity. For example, Hao et al. [11] prepared mesoporous titaniapowders with a bicrystalline (anatase and brookite) framework bya modified sol–gel method. The as-prepared sample showed highphotocatalytic activity to degrade Rhodamine B (RhB), which wasattributed to the porous structure and large surface area. In addi-tion, Zhou et al. [12] synthesized anatase TiO2with mesoporousstructure by a unique hydrothermal process, applied in Lithium-based storage devices as an electrode material. Due to its largeactive surface area, the sample would allow for the use of highelectrochemical reaction rates and is of great importance in batteryapplications
