Control of pore- and crystalline structure of mesoporous titania, which is prepared using surfactant molecular assemblies as structure directing agents, is described focusing on the effect of molecular structure and aggregation state of the surfactant. Following three recent topics are mainly introduced; ① Control of pore structure and size of mesoporous titania using molecular assemblies formed at aqueous mixture of cationic and anionic surfactants as the structure directing agent, ② Preparation of mesoporous titania bearing crystalline wall using molecular assemblies formed by a quarternary ammonium type cationic surfactant as a "self-organized catalyst". ③ Preparation of mesoporous titania photocatalyst responsive to visible light irradiation. It is suggested that highly unique and functional nanoporous titania can be prepared using the interface of molecular assemblies as the "self-organized catalyst".
