“…Likewise, Dai and co-workers [ 64 ] were able to determine the particle size of TiO 2 thin films using DRS. Several other works employed DRS to determine band gap and particle size for TiO 2 prepared by the EISA method [ 38 , 45 , 52 , 129 , 139 ]. The research works taken together points to the versatility of DRS for obtaining the type of crystallographic phase, bandgap, and particle size.…”

“…Anatase TiO 2 with smaller pore diameter and crystallite size yielded less hydrogen, perhaps due to enhanced surface recombination of electron-hole pairs. Park and co-workers [ 139 ] indicated that surface area plays a major role and observed hydrogen evolution rate of 160 μmol in 200 min. in their highest active mesoporous TiO 2 powders.…”

Evaporation-Induced Self-Assembly (EISA) method for the preparation of mesoporous titanium dioxide materials is reviewed. The versatility of EISA method for the rapid and facile synthesis of TiO2 thin films and powders is highlighted. Non-ionic surfactants such as Pluronic P123, F127 and cationic surfactants such as cetyltrimethylammonium bromide have been extensively employed for the preparation of mesoporous TiO2. In particular, EISA method allows for fabrication of highly uniform, robust, crack-free films with controllable thickness. Eleven characterization techniques for elucidating the structure of the EISA prepared mesoporous TiO2 are discussed in this paper. These many characterization methods provide a holistic picture of the structure of mesoporous TiO2. Mesoporous titanium dioxide materials have been employed in several applications that include Dye Sensitized Solar Cells (DSSCs), photocatalytic degradation of organics and splitting of water, and batteries.
